+<h1>Kemono Downloader - Comprehensive Feature Guide</h1>
+<p>This guide provides a detailed overview of all user interface elements, input fields, buttons, popups, and functionalities available in the application.</p>
+<hr>
+<h2>1. Core Concepts &amp; Supported Sites</h2>
+<h3>URL Input (🔗)</h3>
+<p>This is the primary input field where you specify the content you want to download.</p>
+<p><strong>Supported URL Types:</strong></p>
+<ul>
+  <li><strong>Creator URL</strong>: A link to a creator's main page. Downloads all posts from that creator.</li>
+  <li><strong>Post URL</strong>: A direct link to a specific post. Downloads only that single post.</li>
+  <li><strong>Batch Command</strong>: Special keywords to trigger bulk downloading from a text file (see Batch Downloading section).</li>
+</ul>
+<p><strong>Supported Websites:</strong></p>
+<ul>
+  <li>Kemono (<code>kemono.su</code>, <code>kemono.party</code>, etc.)</li>
+  <li>Coomer (<code>coomer.su</code>, <code>coomer.party</code>, etc.)</li>
+  <li>Discord (via Kemono/Coomer API)</li>
+  <li>Bunkr</li>
+  <li>Erome</li>
+  <li>Saint2.su</li>
+  <li>nhentai</li>
+</ul>
+<hr>
+<h2>2. Main Download Controls &amp; Inputs</h2>
+<h3>Download Location (📁)</h3>
+<p>This input defines the main folder where your files will be saved.</p>
+<ul>
+  <li><strong>Browse Button</strong>: Opens a system dialog to choose a folder.</li>
+  <li><strong>Directory Creation</strong>: If the folder doesn't exist, the app will ask for confirmation to create it.</li>
+</ul>
+<h3>Filter by Character(s) &amp; Scope</h3>
+<p>Used to download content for specific characters or series and organize them into subfolders.</p>
+<ul>
+  <li><strong>Input Field</strong>: Enter comma-separated names (e.g., <code>Tifa, Aerith</code>). Group aliases using parentheses for folder naming (e.g., <code>(Cloud, Zack)</code>).</li>
+  <li><strong>Scope Button</strong>: Cycles through where to look for name matches:
+    <ul>
+      <li><strong>Filter: Title</strong>: Matches names in the post title.</li>
+      <li><strong>Filter: Files</strong>: Matches names in the filenames.</li>
+      <li><strong>Filter: Both</strong>: Checks the title first, then filenames.</li>
+      <li><strong>Filter: Comments</strong>: Checks filenames first, then post comments.</li>
+    </ul>
+  </li>
+</ul>
+<h3>Skip with Words &amp; Scope</h3>
+<p>Prevents downloading content based on keywords or file size.</p>
+<ul>
+  <li><strong>Input Field</strong>: Enter comma-separated keywords (e.g., <code>WIP, sketch, preview</code>).</li>
+  <li><strong>Skip by Size</strong>: Enter a number in square brackets to skip any file <strong>smaller than</strong> that size in MB. For example, <code>WIP, [200]</code> skips files with "WIP" in the name AND any file smaller than 200 MB.</li>
+  <li><strong>Scope Button</strong>: Cycles through where to apply keyword filters:
+    <ul>
+      <li><strong>Scope: Posts</strong>: Skips the entire post if the title matches.</li>
+      <li><strong>Scope: Files</strong>: Skips individual files if the filename matches.</li>
+      <li><strong>Scope: Both</strong>: Checks the post title first, then individual files.</li>
+    </ul>
+  </li>
+</ul>
+<h3>Remove Words from Name (✂️)</h3>
+<p>Enter comma-separated words to remove from final filenames (e.g., <code>patreon, [HD]</code>). This helps clean up file naming.</p>
+<hr>
+<h2>3. Primary Download Modes (Filter File Section)</h2>
+<p>This section uses radio buttons to set the main download mode. Only one can be active at a time.</p>
+<ul>
+  <li><strong>All</strong>: Default mode. Downloads every file and attachment.</li>
+  <li><strong>Images/GIFs</strong>: Downloads only common image formats.</li>
+  <li><strong>Videos</strong>: Downloads only common video formats.</li>
+  <li><strong>Only Archives</strong>: Downloads only <code>.zip</code>, <code>.rar</code>, etc.</li>
+  <li><strong>Only Audio</strong>: Downloads only common audio formats.</li>
+  <li><strong>Only Links</strong>: Extracts external hyperlinks (e.g., Mega, Google Drive) from post descriptions instead of downloading files. <strong>This mode unlocks special features</strong> (see section 6).</li>
+  <li><strong>More</strong>: Opens a dialog to download text-based content.
+    <ul>
+      <li><strong>Scope</strong>: Choose to extract text from the post description or comments.</li>
+      <li><strong>Export Format</strong>: Save as PDF, DOCX, or TXT.</li>
+      <li><strong>Single PDF</strong>: Compile all text from the session into one consolidated PDF file.</li>
+    </ul>
+  </li>
+</ul>
+<hr>
+<h2>4. Advanced Features &amp; Toggles (Checkboxes)</h2>
+<h3>Folder Organization</h3>
+<ul>
+  <li><strong>Separate folders by Known.txt</strong>: Automatically organizes downloads into subfolders based on name matches from your <code>Known.txt</code> list or the "Filter by Character(s)" input.</li>
+  <li><strong>Subfolder per post</strong>: Creates a unique folder for each post, named after the post's title. This prevents files from different posts from mixing.</li>
+  <li><strong>Date prefix</strong>: (Only available with "Subfolder per post") Prepends the post date to the folder name (e.g., <code>2025-08-03 My Post Title</code>) for chronological sorting.</li>
+</ul>
+<h3>Special Modes</h3>
+<ul>
+  <li><strong>⭐ Favorite Mode</strong>: Switches the UI to download from your personal favorites list instead of using the URL input.</li>
+  <li><strong>Manga/Comic mode</strong>: Sorts a creator's posts from oldest to newest before downloading, ensuring correct page order. A scope button appears to control the filename style (e.g., using post title, date, or a global number).</li>
+</ul>
+<h3>File Handling</h3>
+<ul>
+  <li><strong>Skip Archives</strong>: Ignores <code>.zip</code> and <code>.rar</code> files during downloads.</li>
+  <li><strong>Download Thumbnail Only</strong>: Saves only the small preview images instead of full-resolution files.</li>
+  <li><strong>Scan Content for Images</strong>: Parses post HTML to find embedded images that may not be listed in the API data.</li>
+  <li><strong>Compress to WebP</strong>: Converts large images (over 1.5 MB) to the space-saving WebP format.</li>
+  <li><strong>Keep Duplicates</strong>: Opens a dialog to control how duplicate files are handled (skip by default, keep all, or keep a specific number of copies).</li>
+</ul>
+<h3>General Functionality</h3>
+<ul>
+  <li><strong>Use cookie</strong>: Enables login-based access. You can paste a cookie string or browse for a <code>cookies.txt</code> file.</li>
+  <li><strong>Use Multithreading</strong>: Enables parallel processing of posts for faster downloads. You can set the number of concurrent worker threads.</li>
+  <li><strong>Show external links in log</strong>: Opens a secondary log panel that displays external links found in post descriptions.</li>
+</ul>
+<hr>
+<h2>5. Specialized Downloaders &amp; Batch Mode</h2>
+<h3>Discord Features</h3>
+<ul>
+  <li>When a Discord URL is entered, a <strong>Scope</strong> button appears.
+    <ul>
+      <li><strong>Scope: Files</strong>: Downloads all files from the channel/server.</li>
+      <li><strong>Scope: Messages</strong>: Saves the entire message history of the channel/server as a formatted PDF.</li>
+    </ul>
+  </li>
+  <li>A <strong>"Save as PDF"</strong> button also appears as a shortcut for the message saving feature.</li>
+</ul>
+<h3>Batch Downloading (<code>nhentai</code> &amp; <code>saint2.su</code>)</h3>
+<p>This feature allows you to download hundreds of galleries or videos from a simple text file.</p>
+<ol>
+  <li>In the <code>appdata</code> folder, create <code>nhentai.txt</code> or <code>saint2.su.txt</code>.</li>
+  <li>Add one full URL per line to the corresponding file.</li>
+  <li>In the app's URL input, type either <code>nhentai.net</code> or <code>saint2.su</code> and click "Start Download".</li>
+  <li>The app will read the file and process every URL in the queue.</li>
+</ol>
+<hr>
+<h2>6. "Only Links" Mode: Extraction &amp; Direct Download</h2>
+<p>When you select the <strong>"Only Links"</strong> radio button, the application's behavior changes significantly.</p>
+<ul>
+  <li><strong>Link Extraction</strong>: Instead of downloading files, the main log panel will fill with all external links found (Mega, Google Drive, Dropbox, etc.).</li>
+  <li><strong>Export Links</strong>: An "Export Links" button appears, allowing you to save the full list of extracted URLs to a <code>.txt</code> file.</li>
+  <li><strong>Direct Cloud Download</strong>: A <strong>"Download"</strong> button appears next to the export button.
+    <ul>
+      <li>Clicking this opens a new dialog listing all supported cloud links (Mega, G-Drive, Dropbox).</li>
+      <li>You can select which files you want to download from this list.</li>
+      <li>The application will then download the selected files directly from the cloud service to your chosen download location.</li>
+    </ul>
+  </li>
+</ul>
+<hr>
+<h2>7. Session &amp; Process Management</h2>
+<h3>Main Action Buttons</h3>
+<ul>
+  <li><strong>Start Download</strong>: Begins the download process. This button's text changes contextually (e.g., "Extract Links", "Check for Updates").</li>
+  <li><strong>Pause / Resume</strong>: Pauses or resumes the ongoing download. When paused, you can safely change some settings.</li>
+  <li><strong>Cancel &amp; Reset UI</strong>: Stops the current download and performs a soft reset of the UI, preserving your URL and download location.</li>
+</ul>
+<h3>Restore Interrupted Download</h3>
+<p>If the application is closed unexpectedly during a download, it will save its progress.</p>
+<ul>
+  <li>On the next launch, the UI will be pre-filled with the settings from the interrupted session.</li>
+  <li>The <strong>Pause</strong> button will change to <strong>"🔄 Restore Download"</strong>. Clicking it will resume the download exactly where it left off, skipping already processed posts.</li>
+  <li>The <strong>Cancel</strong> button will change to <strong>"🗑️ Discard Session"</strong>, allowing you to clear the saved state and start fresh.</li>
+</ul>
+<h3>Other UI Controls</h3>
+<ul>
+  <li><strong>Error Button</strong>: Shows a count of failed files. Clicking it opens a dialog where you can view, export, or retry the failed downloads.</li>
+  <li><strong>History Button</strong>: Shows a log of recently downloaded files and processed posts.</li>
+  <li><strong>Settings Button</strong>: Opens the settings dialog where you can change the theme, language, and <strong>check for application updates</strong>.</li>
+  <li><strong>Support Button</strong>: Opens a dialog with links to the project's source code and developer support pages.</li>
+</ul>

+# 🛠️ KemonoDownloader Refactor Notes
+
+## What's Going On
+
+This project used to be one giant messy App Script. It worked, but it was hard to maintain or expand. So I cleaned it up and split everything into smaller, more manageable files to make it easier to read, update, and add new stuff later.
+
+**⚠️ Heads up:** Since I'm still in the middle of refactoring things, some features might be broken or not working right now. The layout is better, but I still need to update some parts of the logic and dependencies.

+## ✅ Why Bother Refactoring?
+
+- Everything’s now broken into smaller parts, so it’s easier to work with.
+- Easier to test, fix, and add stuff.
+- Prepping the project to grow without becoming a mess again.
+- Separated the UI from the app logic so they don’t get tangled.
+
+---
+
+## 🚧 What’s Still Broken
+
+- Some features don’t work yet or haven’t been tested since the changes.
+- Still need to:
+  - Reconnect the UI to the updated logic.
+  - Move over some of the old script code into proper modules.
+  - Make sure settings and cookies work properly in the new setup.
+
+---
+
+## 📌 To-Do List
+
+- Test all the dialogs and UI stuff.
+- Make sure the download services and API calls are working.
+- Reconnect the UI with the new logic in `core/manager.py`.
+- Add more logging and maybe some unit tests too.
+
+---
+
+## 🐞 Found a Bug?
+
+If something's busted:
+
+- Feel free to open an issue if you're using this.
+- Or just message me. Feedback helps a lot while I’m still figuring things out.
+
+Thanks for checking it out! Still a work in progress, but getting there.

-##  What's New in v4.1.1? - Enhanced Image Discovery & Audio Filtering
-
-Version 4.1.1 brings significant enhancements, including smarter image capture from post content and a dedicated filter mode for audio files.
-
-###  "Scan Content for Images" Feature
-
-- **Enhanced Image Discovery:** A new checkbox, "**Scan Content for Images**," has been added to the UI (grouped with "Download Thumbnails Only" and "Compress Large Images").
-- **How it Works:**
-    - When enabled, the downloader meticulously scans the HTML content of each post's description or body.
-    - It searches for images in two main ways:
-        - **Directly linked absolute URLs** (e.g., `https://externalsite.com/image.png`) that end with a common image extension (jpg, png, gif, etc.).
-        - **Images embedded using HTML `<img>` tags.** The downloader extracts the `src` attribute from these tags and can resolve various path types:
-            - Absolute URLs (e.g., `http://...` or `https://...`)
-            - Protocol-relative URLs (e.g., `//cdn.example.com/image.jpg`)
-            - Root-relative paths (e.g., `/data/user_content/image.gif`), which are resolved against the site's base URL (like `https://kemono.su/data/user_content/image.gif`).
-    - This is particularly useful for capturing images that are part of the post's narrative but not formally listed in the API's file or attachment sections.
-- **Default State:** This option is **unchecked by default**.
-- **Key Interaction with "Download Thumbnails Only":** This new feature works closely with the existing "Download Thumbnails Only" option:
-    - If you enable "Download Thumbnails Only":
-        - The "Scan Content for Images" checkbox will **automatically become checked and disabled** (locked).
-        - The downloader then **exclusively downloads images discovered through the content scan**. Any API-listed thumbnails are bypassed, giving priority to images embedded directly in the post.
-    - If you disable "Download Thumbnails Only":
-        - The "Scan Content for Images" checkbox will become **enabled again and revert to being unchecked**. You can then manually enable it if you wish to scan content without being in thumbnail-only mode.
-
-This feature ensures a more comprehensive download experience, especially for posts where images are integrated directly into the text.
-
-### New "🎧 Only Audio" Filter Mode
-
-Alongside image discovery, v4.1.1 also introduces/enhances a dedicated filter mode for audio enthusiasts:
-
--   **Focused Audio Downloads:** The "🎧 Only Audio" option in the "Filter Files" radio button group allows you to download exclusively common audio file types. This includes formats like MP3, WAV, FLAC, M4A, OGG, and more.
--   **Streamlined UI:** When "🎧 Only Audio" mode is active:
-    -   Irrelevant UI options such as the "Skip Scope" button (for word-based post/file skipping) and the "Multi-part Download" toggle are hidden to simplify the interface.
-    -   The "Show External Links in Log" checkbox is automatically disabled, as link extraction is not the focus of this mode.
--   **Archive Handling:** Unlike the "📦 Only Archives" mode (which disables archive skipping), the "Skip .zip" and "Skip .rar" checkboxes remain enabled and configurable when "🎧 Only Audio" is selected. This gives you the flexibility to also exclude any archives encountered while in audio-only mode if desired.
--   **Purpose:** This mode is perfect for users who primarily want to collect audio tracks, podcasts, or sound effects from posts without downloading other media types.
-
-
----
-
-##  Previous Update: What's New in v4.0.1?
-
-Version 4.0.1 focuses on enhancing access to content and providing even smarter organization:
-
-###  Cookie Management
-
-- **Access Content:** Seamlessly download from Kemono/Coomer as if you were logged in by using your browser's cookies.
-- **Flexible Input:**
-  - Directly paste your cookie string (e.g., `name1=value1; name2=value2`).
-  - Browse and load cookies from a `cookies.txt` file (Netscape format).
-  - Automatic fallback to a `cookies.txt` file in the application directory if "Use Cookie" is enabled and no other source is specified.
-- **Easy Activation:** A simple "Use Cookie" checkbox in the UI controls this feature.
-- *Important Note: Cookie settings (text, file path, and enabled state) are configured per session and are not saved when the application is closed. You will need to re-apply them on each launch if needed.*
-

-
-###  Advanced `Known.txt` and Character Filtering
-
-The `Known.txt` system has been revamped for improved performance and stability. The previous method of handling known names could become resource-intensive with large lists, potentially leading to application slowdowns or crashes. This new, streamlined system offers more direct control and robust organization.
-The `Known.txt` file and the "Filter by Character(s)" input field work together to provide powerful and flexible content organization. The `Known.txt` file itself has a straightforward syntax, while the UI input allows for more complex session-specific grouping and alias definitions that can then be added to `Known.txt`.
-
-**1. `Known.txt` File Syntax (Located in App Directory):**
-
-`Known.txt` stores your persistent list of characters, series, or keywords for folder organization. Each line is an entry:
-
-- **Simple Entries:**
-  - A line like `My Awesome Series` or `Nami`.
-  - **Behavior:** Content matching this term will be saved into a folder named "My Awesome Series" or "Nami" respectively (if "Separate Folders" is enabled).
-
-**2. "Filter by Character(s)" UI Input Field:**
-
-This field allows for dynamic filtering for the current download session and provides options for how new entries are added to `Known.txt`.
-
-- **Standard Names:**
-  - Input: `Nami, Robin`
-  - Session Behavior: Filters for "Nami" OR "Robin". If "Separate Folders" is on, creates folders "Nami" and "Robin".
-  - `Known.txt` Addition: If "Nami" is new and selected for addition in the confirmation dialog, it's added as `Nami` on a new line in `Known.txt`.
-
-- **Grouped Aliases for a Single Character (using `(...)~` syntax):**
-  - Input: `(Boa, Hancock)~`
-  - Meaning: "Boa" and "Hancock" are different names/aliases for the *same character*. The names are listed within parentheses separated by commas (e.g., `name1, alias1, alias2`), and the entire group is followed by a `~` symbol. This is useful when a creator uses different names for the same character.
-  - Session Behavior: Filters for "Boa" OR "Hancock". If "Separate Folders" is on, creates a single folder named "Boa Hancock".
-  - `Known.txt` Addition: If this group is new and selected for addition, it's added to `Known.txt` as a grouped alias entry, typically `(Boa Hancock)`. The first name in the `Known.txt` entry (e.g., "Boa Hancock") becomes the primary folder name.
-
-- **Combined Folder for Distinct Characters (using `(...)` syntax):**
-  - Input: `(Vivi, Uta)`
-  - Meaning: "Vivi" and "Uta" are *distinct characters*, but for this download session, their content should be grouped into a single folder. The names are listed within parentheses separated by commas. This is useful for grouping art of less frequent characters without creating many small individual folders.
-  - Session Behavior: Filters for "Vivi" OR "Uta". If "Separate Folders" is on, creates a single folder named "Vivi Uta".
-  - `Known.txt` Addition: If this "combined group" is new and selected for addition, "Vivi" and "Uta" are added to `Known.txt` as *separate, individual simple entries* on new lines:
-    ```
-    Vivi
-    Uta
-    ```
-    The combined folder "Vivi Uta" is a session-only convenience; `Known.txt` stores them as distinct entities for future individual use.
-
-**3. Interaction with `Known.txt`:**
-
-- **Adding New Names from Filters:** When you use the "Filter by Character(s)" input, if any names or groups are new (not already in `Known.txt`), a dialog will appear after you start the download. This dialog allows you to select which of these new names/groups should be added to `Known.txt`, formatted according to the rules described above.
-- **Intelligent Fallback:** If "Separate Folders by Name/Title" is active, and content doesn't match the "Filter by Character(s)" UI input, the downloader consults your `Known.txt` file for folder naming.
-- **Direct Management:** You can add simple entries directly to `Known.txt` using the list and "Add" button in the UI's `Known.txt` management section. For creating or modifying complex grouped alias entries directly in the file, or for bulk edits, click the "Open Known.txt" button. The application reloads `Known.txt` on startup or before a download process begins.
-- **Using Known Names to Populate Filters (via "Add to Filter" Button):**
-  - Next to the "Add" button in the `Known.txt` management section, a "⤵️ Add to Filter" button provides a quick way to use your existing known names.
-  - Clicking this opens a popup window displaying all entries from your `Known.txt` file, each with a checkbox.
-  - The popup includes:
-    - A search bar to quickly filter the list of names.
-    - "Select All" and "Deselect All" buttons for convenience.
-  - After selecting the desired names, click "Add Selected".
-  - The chosen names will be inserted into the "Filter by Character(s)" input field.
-  - **Important Formatting:** If a selected entry from `Known.txt` is a group (e.g., originally `(Boa Hancock)` in `Known.txt`, which implies aliases "Boa" and "Hancock"), it will be added to the filter field as `(Boa, Hancock)~`. Simple names are added as-is.
-
-
----
-##  What's in v3.5.0? (Previous Update)
-This version brought significant enhancements to manga/comic downloading, filtering capabilities, and user experience:
-
-###  Enhanced Manga/Comic Mode
-
-- **Optional Filename Prefix:**
-  - When using the "Date Based" or "Original File Name" manga styles, an optional prefix can be specified in the UI.
-  - This prefix will be prepended to each filename generated by these styles.
-  - **Example (Date Based):** If prefix is `MySeries_`, files become `MySeries_001.jpg`, `MySeries_002.png`, etc.
-  - **Example (Original File Name):** If prefix is `Comic_Vol1_`, an original file `page_01.jpg` becomes `Comic_Vol1_page_01.jpg`.
-  - This input field appears automatically when either of these two manga naming styles is selected.
-
-- **New "Date Based" Filename Style:**
-
-  - Perfect for truly sequential content! Files are named numerically (e.g., `001.jpg`, `002.jpg`, `003.ext`...) across an *entire creator's feed*, strictly following post publication order.
-
-  - **Smart Numbering:** Automatically resumes from the highest existing number found in the series folder (and subfolders, if "Subfolder per Post" is enabled).
-
-  - **Guaranteed Order:** Disables multi-threading for post processing to ensure sequential accuracy.
-
-  - Works alongside the existing "Post Title" and "Original File Name" styles.
-- **New "Title+G.Num (Post Title + Global Numbering)" Filename Style:**
-  - Ideal for series where you want each file to be prefixed by its post title but still maintain a global sequential number across all posts from a single download session.
-  - **Naming Convention:** Files are named using the cleaned post title as a prefix, followed by an underscore and a globally incrementing number (e.g., `Post Title_001.ext`, `Post Title_002.ext`).
-  - **Example:**
-    - Post "Chapter 1: The Adventure Begins" (contains 2 files: `imageA.jpg`, `imageB.png`) -> `Chapter 1 The Adventure Begins_001.jpg`, `Chapter 1 The Adventure Begins_002.png`
-    - Next Post "Chapter 2: New Friends" (contains 1 file: `cover.jpg`) -> `Chapter 2 New Friends_003.jpg`
-  - **Sequential Integrity:** Multithreading for post processing is automatically disabled when this style is selected to ensure the global numbering is strictly sequential.
-
----
-
-###  "Remove Words from Filename" Feature
-
-- Specify comma-separated words or phrases (case-insensitive) that will be automatically removed from filenames.
-
-- Example: `patreon, [HD], _final` transforms `AwesomeArt_patreon` `Hinata_Hd` into `AwesomeArt.jpg` `Hinata.jpg`.
-
----
-
-###  New "Only Archives" File Filter Mode
-
-- Exclusively downloads `.zip` and `.rar` files.
-
-- Automatically disables conflicting options like "Skip .zip/.rar" and external link logging.
-
----
-
-###  Improved Character Filter Scope - "Comments (Beta)"
-
-- **File-First Check:** Prioritizes matching filenames before checking post comments for character names.
-
-- **Comment Fallback:** Only checks comments if no filename match is found, reducing unnecessary API calls.
-
----
-
-###  Refined "Missed Character Log"
-
-- Displays a capitalized, alphabetized list of key terms from skipped post titles.
-
-- Makes it easier to spot patterns or characters that might be unintentionally excluded.
-
----
-
-###  Enhanced Multi-part Download Progress
-
-- Granular visibility into active chunk downloads and combined speed for large files.
-
----
-
-###  Updated Onboarding Tour
-
-- Improved guide for new users, covering v4.0.0 features and existing core functions.
-
----
-
-###  Robust Configuration Path
-
-- Settings and `Known.txt` are now stored in the same folder as app.
-
----
-
-##  Core Features
-
----
-
-### User Interface & Workflow
-
-- **Clean PyQt5 GUI** — Simple, modern, and dark-themed.
-
-- **Persistent Settings** — Saves preferences between sessions.
-
-- **Download Modes:**
-  - Single Post URL
-  - Entire Creator Feed
-
-- **Flexible Options:**
-  - Specify Page Range (disabled in Manga Mode)
-  - Custom Folder Name for single posts
-
----
-
-###  Smart Filtering
-
-- **Character Name Filtering:**
-  - Use `Tifa, Aerith` or group `(Boa, Hancock)` → folder `Boa Hancock`
-  - Flexible input for current session and for adding to `Known.txt`.
-  - Examples:
-    - `Nami` (simple character)
-    - `(Boa Hancock)~` (aliases for one character, session folder "Boa Hancock", adds `(Boa Hancock)` to `Known.txt`)
-    - `(Vivi, Uta)` (distinct characters, session folder "Vivi Uta", adds `Vivi` and `Uta` separately to `Known.txt`)
-  - A "⤵️ Add to Filter" button (near the `Known.txt` management UI) allows you to quickly populate this field by selecting from your existing `Known.txt` entries via a popup with search and checkbox selection.
-  - See "Advanced `Known.txt` and Character Filtering" for full details.
-  - **Filter Scopes:**
-    - `Files`
-    - `Title`
-    - `Both (Title then Files)`
-    - `Comments (Beta - Files first)`
-
-- **Skip with Words:**
-  - Exclude with `WIP, sketch, preview`
-
-  - **Skip Scopes:**
-    - `Files`
-    - `Posts`
-    - `Both (Posts then Files)`
-
-- **File Type Filters:**
-  - `All`, `Images/GIFs`, `Videos`, `📦 Only Archives`, `🔗 Only Links`
-
-- **Filename Cleanup:**
-  - Remove illegal and unwanted characters or phrases
-
----
-
-### Manga/Comic Mode (Creator Feeds Only)
-
-- **Chronological Processing** — Oldest posts first
-
-- **Filename Style Options:**
-  - `Name: Post Title (Default)`
-  - `Name: Original File`
-  - `Name: Date Based (New)`
-  - `Name: Title+G.Num (Post Title + Global Numbering)`
-
-- **Best With:** Character filters set to manga/series title
-
----
-
-### Folder Structure & Naming
-
-- **Subfolders:**
-  - Auto-created based on character name, post title, or `Known.txt`
-
-  - "Subfolder per Post" option for further nesting
-
-- **Smart Naming:** Cleans invalid characters and structures logically
-
----
-
-### Thumbnail & Compression Tools
-- **Download Thumbnails Only:**
-  - Downloads small preview images from the API instead of full-sized files (if available).
-  - **Interaction with "Scan Content for Images" (New in v4.1.1):** When "Download Thumbnails Only" is active, "Scan Content for Images" is auto-enabled, and only images found by the content scan are downloaded. See "What's New in v4.1.1" for details.
-- **Scan Content for Images (New in v4.1.1):**
-  - A UI option to scan the HTML content of posts for embedded image URLs (from `<img>` tags or direct links).
-  - Resolves relative paths and helps capture images not listed in the API's formal attachments.
-  - See the "What's New in v4.1.1?" section for a comprehensive explanation.
-- **Compress to WebP** (via Pillow)
-  - Converts large images to smaller WebP versions
-
-
----
-
-###  Performance Features
-
-- **Multithreading:**
-  - For both post processing and file downloading
-
-- **Multi-part Downloads:**
-  - Toggleable in GUI
-  - Splits large files into chunks
-  - Granular chunk-level progress display
-
----
-
-### Logging & Progress
-
-- **Real-time Logs:** Activity, errors, skipped posts
-
-- **Missed Character Log:** Shows skipped keywords in easy-to-read list
-
-- **External Links Log:** Shows links (unless disabled in some modes)
-
-- **Export Links:** Save `.txt` of links (Only Links mode)
-
----
-
-###  Config System
-
-- **`Known.txt` for Smart Folder Naming (Located in App Directory):**
-  - A user-editable file that stores a list of preferred names, series titles, or keywords.
-  - It's primarily used as an intelligent fallback for folder creation when "Separate Folders by Name/Title" is enabled.
-  - **Syntax:**
-    - Simple entries: `My Favorite Series` (creates folder "My Favorite Series", matches "My Favorite Series").
-    - Grouped entries: `(Desired Folder Name, alias1, alias2)` (creates folder "Desired Folder Name"; matches "Desired Folder Name", "alias1", or "alias2").
-
-- **Settings Stored in App Directory**
-
-- **Editable Within GUI**

+             <h3 style='color: #E0E0E0;'>How to Use Favorite Mode</h3>
+             <ol>
+                 <li>Check the <b>"⭐ Favorite Mode"</b> checkbox on the main window. This will lock the URL bar and show two new buttons.</li>
+                 <li>Click either <b>"🖼️ Favorite Artists"</b> or <b>"📄 Favorite Posts"</b>.</li>
+                 <li>A new dialog will open and begin fetching all your favorites from both Kemono and Coomer at the same time.</li>
+                 <li>Once loaded, you can search, filter, and select the artists or posts you want to download.</li>
+                 <li>Click "Download Selected" to add them to the main download queue and begin processing.</li>
+             </ol>
+             
+             <h3 style='color: #E0E0E0;'>Favorite Artists</h3>
+             <p>The <b>"Favorite Artists"</b> dialog will load your list of followed creators. When you download from here, the app treats it as a full creator download, just as if you had pasted in that artist's URL.</p>
+             
+             <h3 style='color: #E0E0E0;'>Favorite Posts</h3>
+             <p>The <b>"Favorite Posts"</b> dialog loads a list of every individual post you have favorited. This dialog has some extra features:</p>
+             <ul>
+                 <li><b>Creator Name Resolution:</b> It attempts to match the post's creator ID with the names in your <code>creators.json</code> file to show you a recognizable name.</li>
+                 <li><b>Known.txt Matching:</b> It highlights posts by showing <code>[Known - Tifa]</code> in the title if the post title matches an entry in your <code>Known.txt</code> list, helping you find specific content.</li>
+                 <li><b>Grouping:</b> Posts are automatically grouped by creator to keep the list organized.</li>
+             </ul>
+
+             <h3 style='color: #E0E0E0;'>Download Scope (Artist Folders)</h3>
+             <p>In Favorite Mode, the <b>"Scope: [Location]"</b> button becomes very important. It controls <i>where</i> your favorited items are saved:</p>
+             <ul>
+                 <li><b>Scope: Selected Location (Default):</b> Downloads all selected items directly into the main "Download Location" folder you have set.</li>
+                 <li><b>Scope: Artist Folders:</b> This automatically creates a new subfolder for each artist inside your main "Download Location" (e.g., <code>/Downloads/ArtistName/</code>). This is the best way to keep your favorites organized.</li>
+             </ul>
+             """),
+
+            ("File & Download Options",
+             """
+             <p>These checkboxes give you fine-grained control over which files are downloaded and how they are processed.</p>
+             
+             <h3 style='color: #E0E0E0;'>File Type & Content</h3>
+             <ul>
+                 <li><b>Skip .zip:</b> A simple toggle. When checked, the downloader will skip all <code>.zip</code> and <code>.rar</code> archive files it finds.</li>
+                 <br>
+                 <li><b>Scan Content for Images:</b> This is a powerful feature for posts where images are embedded in the description (<code>&lt;img&gt;</code> tags) but not listed as attachments. When checked, the app will scan the post's HTML content and try to find and download these embedded images.</li>
+             </ul>
+
+             <h3 style='color: #E0E0E0;'>Image Processing</h3>
+             <ul>
+                 <li><b>Download Thumbnails Only:</b> Saves bandwidth and time by downloading the small preview/thumbnail version of an image instead of the full-resolution file.</li>
+                 <br>
+                 <li><b>Compress to WebP:</b> If an image is over 1.5MB, this option will automatically convert it to the <code>.webp</code> format during the download, which significantly reduces file size while maintaining high quality.</li>
+             </ul>
+
+             <h3 style='color: #E0E0E0;'>Duplicate Handling</h3>
+             <ul>
+                 <li><b>Keep Duplicates:</b> By default, the app checks the <i>content</i> (hash) of a file and will not re-download a file it already has. Checking this box opens a dialog with more options:
+                    <ul>
+                        <li><b>Hash (Default):</b> The standard behavior.</li>
+                        <li><b>Keep Everything:</b> Disables all duplicate checks and downloads every file from the API, even if you already have it.</li>
+                        <li><b>Limit:</b> Lets you set a limit (e.g., 2) to how many times a file with the same content can be downloaded.</li>
+                    </ul>
+                 </li>
+             </ul>
+             """),
+
+            ("Utility & Advanced Options",
+             """
+             <p>These features provide advanced control over your downloads, sessions, and application settings.</p>
+             
+             <h3 style='color: #E0E0E0;'>Use Cookie</h3>
+             <p>This is essential for downloading from sites that require a login (like <b>SimpCity</b> or accessing your <b>favorites</b> on Kemono/Coomer). You can either:</p>
+             <ul>
+                 <li><b>Paste a cookie string:</b> Copy the "cookie" value from your browser's developer tools and paste it into the text field.</li>
+                 <li><b>Use a file:</b> Click the "Browse" button to select a <code>cookies.txt</code> file exported from your browser.</li>
+             </ul>
+
+             <h3 style='color: #E0E0E0;'>Page Range</h3>
+             <p>When downloading from a creator's main page (not a single post), these "Start" and "End" fields let you limit the download. For example, entering <code>Start: 1</code> and <code>End: 5</code> will only download posts from the first five pages.</p>
+             
+             <h3 style='color: #E0E0E0;'>Multi-part Download</h3>
+             <p>Clicking the <b>"Multi-part: OFF"</b> button opens a dialog to enable high-speed downloads for large files. It will split a large file into multiple parts and download them at the same time. You can choose to apply this to videos, archives, or both, and set the minimum file size to trigger it.</p>
+             
+             <h3 style='color: #E0E0E0;'>Download History</h3>
+             <p>The <b>"History"</b> button opens a dialog showing two lists:</p>
+             <ul>
+                 <li><b>Last 3 Files:</b> The last 3 individual files you successfully downloaded.</li>
+                 <li><b>First 3 Posts:</b> The first 3 posts Processed from your *most recent* download session.</li>
+             </ul>
+
+             <h3 style='color: #E0E0E0;'>Settings (Gear Icon)</h3>
