+    <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><strong>Main Window: Core Functionality</strong></h2>
+    <p>The application is divided into a configuration panel on the left and a status/log panel on the right.</p>
+    <h3><strong>Primary Inputs (Top-Left)</strong></h3>
+    <ul>
+        <li><strong>URL Input Field</strong>: This is the starting point for most downloads. You can paste a URL for a specific post or for an entire creator's feed. The application's behavior adapts based on the URL type.</li>
+        <li><strong>🎨 Creator Selection Popup</strong>: This button opens a powerful dialog listing all known creators. From here, you can:
+            <ul>
+                <li><strong>Search and Queue</strong>: Search for creators and check multiple names. Clicking "Add Selected" populates the main input field, preparing a batch download.</li>
+                <li><strong>Check for Updates</strong>: Select a single creator's saved profile. This loads their information and switches the main download button to "Check for Updates" mode, allowing you to download only new content since your last session.</li>
+            </ul>
+        </li>
+        <li><strong>Download Location</strong>: The primary folder where all content will be saved. The <strong>Browse...</strong> button lets you select this folder from your computer.</li>
+        <li><strong>Page Range (Start/End)</strong>: These fields activate only for creator feed URLs. They allow you to download a specific slice of a creator's history (e.g., pages 5 through 10) instead of their entire feed.</li>
+    </ul>
+    <hr>
+    <h2><strong>Filtering & Naming (Left Panel)</strong></h2>
+    <p>These features give you precise control over what gets downloaded and how it's named and organized.</p>
+    <ul>
+        <li><strong>Filter by Character(s)</strong>: A powerful tool to download content featuring specific characters. You can enter multiple names separated by commas.
+            <ul>
+                <li><strong>Filter: [Scope] Button</strong>: This button changes how the character filter works:
+                    <ul>
+                        <li><strong>Title</strong>: Downloads posts only if a character's name is in the post title.</li>
+                        <li><strong>Files</strong>: Downloads posts if a character's name is in any of the filenames within the post.</li>
+                        <li><strong>Both</strong>: Combines the "Title" and "Files" logic.</li>
+                        <li><strong>Comments (Beta)</strong>: Downloads a post if a character's name is mentioned in the comments section.</li>
+                    </ul>
+                </li>
+            </ul>
+        </li>
+        <li><strong>Skip with Words</strong>: A keyword-based filter to avoid unwanted content (e.g., <code>WIP</code>, <code>sketch</code>).
+            <ul>
+                <li><strong>Scope: [Type] Button</strong>: This button changes how the skip filter works:
+                    <ul>
+                        <li><strong>Posts</strong>: Skips the entire post if a keyword is found in the title.</li>
+                        <li><strong>Files</strong>: Skips only individual files if a keyword is found in the filename.</li>
+                        <li><strong>Both</strong>: Applies both levels of skipping.</li>
+                    </ul>
+                </li>
+            </ul>
+        </li>
+        <li><strong>Remove Words from name</strong>: Automatically cleans downloaded filenames by removing any specified words (e.g., "patreon," "HD").</li>
+    </ul>
+    <h3><strong>File Type Filter (Radio Buttons)</strong></h3>
+    <p>This section lets you choose the kind of content you want:</p>
+    <ul>
+        <li><strong>All, Images/GIFs, Videos, 🎧 Only Audio, 📦 Only Archives</strong>: These options filter the downloads to only include the selected file types.</li>
+        <li><strong>🔗 Only Links</strong>: This special mode doesn't download any files. Instead, it scans post descriptions and lists all external links (like Mega, Google Drive) in the log panel.</li>
+        <li><strong>More</strong>: Opens a dialog for text-only downloads. You can choose to save post <strong>descriptions</strong> or <strong>comments</strong> as formatted <strong>PDF, DOCX, or TXT</strong> files. A key feature here is the <strong>"Single PDF"</strong> option, which compiles the text from all downloaded posts into one continuous, sorted PDF document.</li>
+    </ul>
+    <hr>
+    <h2><strong>Download Options & Advanced Settings (Checkboxes)</strong></h2>
+    <ul>
+        <li><strong>Skip .zip</strong>: A simple toggle to ignore archive files during downloads.</li>
+        <li><strong>Download Thumbnails Only</strong>: Downloads only the small preview images instead of the full-resolution files.</li>
+        <li><strong>Scan Content for Images</strong>: A crucial feature that scans the post's text content for embedded images that may not be listed in the API, ensuring a more complete download.</li>
+        <li><strong>Compress to WebP</strong>: Saves disk space by automatically converting large images into the efficient WebP format.</li>
+        <li><strong>Keep Duplicates</strong>: Opens a dialog to control how files with identical content are handled. The default is to skip duplicates, but you can choose to keep all of them or set a specific limit (e.g., "keep up to 2 copies of the same file").</li>
+        <li><strong>Subfolder per Post</strong>: Organizes downloads by creating a unique folder for each post, named after the post's title.</li>
+        <li><strong>Date Prefix</strong>: When "Subfolder per Post" is on, this adds the post's date to the beginning of the folder name (e.g., <code>2025-07-25 Post Title</code>).</li>
+        <li><strong>Separate Folders by Known.txt</strong>: This enables the automatic folder organization system based on your "Known Names" list.</li>
+        <li><strong>Use Cookie</strong>: Allows the application to use browser cookies to access content that might be behind a paywall or login. You can paste a cookie string directly or use <strong>Browse...</strong> to select a <code>cookies.txt</code> file.</li>
+        <li><strong>Use Multithreading</strong>: Greatly speeds up downloads of creator feeds by processing multiple posts at once. The number of <strong>Threads</strong> can be configured.</li>
+        <li><strong>Show External Links in Log</strong>: When checked, a secondary log panel appears at the bottom of the right side, dedicated to listing any external links found.</li>
+    </ul>
+    <hr>
+    <h2><strong>Known Names Management (Bottom-Left)</strong></h2>
+    <p>This powerful feature automates the creation of organized, named folders.</p>
+    <ul>
+        <li><strong>Known Shows/Characters List</strong>: Displays all the names and groups you've saved.</li>
+        <li><strong>Search...</strong>: Filters the list to quickly find a name.</li>
+        <li><strong>Open Known.txt</strong>: Opens the source file in a text editor for advanced manual editing.</li>
+        <li><strong>Add New Name</strong>:
+            <ul>
+                <li><strong>Single Name</strong>: Typing <code>Tifa Lockhart</code> and clicking <strong>➕ Add</strong> creates an entry that will match "Tifa Lockhart".</li>
+                <li><strong>Group</strong>: Typing <code>(Boa, Hancock, Snake Princess)~</code> and clicking <strong>➕ Add</strong> creates a single entry named "Boa Hancock Snake Princess". The application will then look for "Boa," "Hancock," OR "Snake Princess" in titles/filenames and save any matches into that combined folder.</li>
+            </ul>
+        </li>
+        <li><strong>⤵️ Add to Filter</strong>: Opens a dialog with your full Known Names list, allowing you to check multiple entries and add them all to the "Filter by Character(s)" field at once.</li>
+        <li><strong>🗑️ Delete Selected</strong>: Removes highlighted names from your list.</li>
+    </ul>
+    <hr>
+    <h2><strong>Action Buttons & Status Controls</strong></h2>
+    <ul>
+        <li><strong>⬇️ Start Download / 🔗 Extract Links</strong>: The main action button. Its function is dynamic:
+            <ul>
+                <li><strong>Normal Mode</strong>: Starts the download based on the current settings.</li>
+                <li><strong>Update Mode</strong>: After selecting a creator profile, this button changes to <strong>🔄 Check for Updates</strong>.</li>

+                <li><strong>Link Extraction Mode</strong>: The text changes to <strong>🔗 Extract Links</strong>.</li>
+            </ul>
+        </li>
+        <li><strong>⏸️ Pause / ▶️ Resume Download</strong>: Pauses the ongoing download, allowing you to change certain settings (like filters) on the fly. Click again to resume.</li>
+        <li><strong>❌ Cancel & Reset UI</strong>: Immediately stops all download activity and resets the UI to a clean state, preserving your URL and Download Location inputs.</li>
+        <li><strong>Error Button</strong>: If files fail to download, they are logged. This button opens a dialog listing all failed files and will show a count of errors (e.g., <strong>(5) Error</strong>). From the dialog, you can:
+            <ul>

+    </ul>
+    <hr>
+    <h2><strong>Specialized Modes & Features</strong></h2>
+    <h3><strong>⭐ Favorite Mode</strong></h3>
+    <p>Activating this mode transforms the UI for managing saved collections:</p>
+    <ul>
+        <li>The URL input is disabled.</li>
+        <li>The main action buttons are replaced with:
+            <ul>
+                <li><strong>🖼️ Favorite Artists</strong>: Opens a dialog to browse and queue downloads from your saved favorite creators.</li>
+                <li><strong>📄 Favorite Posts</strong>: Opens a dialog to browse and queue downloads for specific saved favorite posts.</li>

+        </li>
+    </ul>
+    <h3><strong>📖 Manga/Comic Mode</strong></h3>
+    <p>This mode is designed for sequential content and has several effects:</p>
+    <ul>
+        <li><strong>Reverses Download Order</strong>: It fetches and downloads posts from <strong>oldest to newest</strong>.</li>
+        <li><strong>Enables Special Naming</strong>: A <strong><code>Name: [Style]</code></strong> button appears, allowing you to choose how files are named to maintain their correct order (e.g., by Post Title, by Date, or simple sequential numbering like <code>001, 002, 003...</code>).</li>
+        <li><strong>Disables Multithreading (for certain styles)</strong>: To guarantee perfect sequential numbering, multithreading for posts is automatically disabled for certain naming styles.</li>
+    </ul>
+    <h3><strong>Session & Error Management</strong></h3>
+    <ul>
+        <li><strong>Session Restore</strong>: If the application is closed unexpectedly during a download, it will detect the incomplete session on the next launch. The UI will present a <strong>🔄 Restore Download</strong> button to resume exactly where you left off. You can also choose to discard the session.</li>

The application compares the posts on the server with your download history for that creator and will prompt you to download only the new content.</li>
+    </ul>
+    <h3><strong>Logging & Monitoring</strong></h3>
+    <ul>
+        <li><strong>Progress Log</strong>: The main log provides real-time feedback on the download process, including status messages, file saves, skips, and errors.</li>
+        <li><strong>👁️ Log View Toggle</strong>: Switches the log view between the standard <strong>Progress Log</strong> and a <strong>Missed Character Log</strong>, which shows potential character names from posts that were skipped by your filters, helping you discover new names to add to your list.</li>

+# 🛠️ 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.

-###  Advanced `Known.txt` and Character Filtering
+## ✨ What's New in v6.0.0
 
-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`.
+This release focuses on providing more granular control over file organization and improving at-a-glance status monitoring.
 
-**1. `Known.txt` File Syntax (Located in App Directory):**
+### New Features
 
-`Known.txt` stores your persistent list of characters, series, or keywords for folder organization. Each line is an entry:
+- **Live Error Count on Button**  
+  The **"Error" button** now dynamically displays the number of failed files during a download. Instead of opening the dialog, you can quickly see a live count like `(3) Error`, helping you track issues at a glance.
 
-- **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).
+- **Date Prefix for Post Subfolders**  
+  A new checkbox labeled **"Date Prefix"** is now available in the advanced settings.  
+  When enabled alongside **"Subfolder per Post"**, it prepends the post's upload date to the folder name (e.g., `2025-07-11 Post Title`).  
+  This makes your downloads sortable and easier to browse chronologically.
 
-**2. "Filter by Character(s)" UI Input Field:**
+- **Keep Duplicates Within a Post**  
+  A **"Keep Duplicates"** option has been added to preserve all files from a post — even if some have the same name.  
+  Instead of skipping or overwriting, the downloader will save duplicates with numbered suffixes (e.g., `image.jpg`, `image_1.jpg`, etc.), which is especially useful when the same file name points to different media.
 
-This field allows for dynamic filtering for the current download session and provides options for how new entries are added to `Known.txt`.
+### Bug Fixes
 
-- **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.

-##  What's in v3.5.0? (Previous Update)
-This version brings significant enhancements to manga/comic downloading, filtering capabilities, and user experience:
-
-###  Enhanced Manga/Comic Mode
-
-- **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.
+- The downloader now correctly renames large `.part` files when completed, avoiding leftover temp files.
+- The list of failed files shown in the Error Dialog is now saved and restored with your session — so no errors get lost if you close the app.
+- Your selected download location is remembered, even after pressing the **Reset** button.
+- The **Cancel** button is now enabled when restoring a pending session, so you can abort stuck jobs more easily.
+- Internal cleanup logs (like "Deleting post cache") are now excluded from the final download summary for clarity.
 
 ---
 
-###  "Remove Words from Filename" Feature
+## 📅 Next Update Plans
 
-- Specify comma-separated words or phrases (case-insensitive) that will be automatically removed from filenames.
+### 🔖 Post Tag Filtering (Planned for v6.1.0)
 
-- Example: `patreon, [HD], _final` transforms `AwesomeArt_patreon` `Hinata_Hd` into `AwesomeArt.jpg` `Hinata.jpg`.
+A powerful new **"Filter by Post Tags"** feature is planned:
+
+- Filter and download content based on specific post tags.
+- Combine tag filtering with current filters (character, file type, etc.).
+- Use tag presets to automate frequent downloads.
+
+This will provide **much greater control** over what gets downloaded, especially for creators who use tags consistently.
+
+### 📁 Creator Download History (.json Save)
+
+To streamline incremental downloads, a new system will allow the app to:
+
+- Save a `.json` file with metadata about already-downloaded posts.
+- Compare that file on future runs, so only **new** posts are downloaded.
+- Avoids duplication and makes regular syncs fast and efficient.
+
+Ideal for users managing large collections or syncing favorites regularly.

+
+## Troubleshooting
+
+### AttributeError: module 'asyncio' has no attribute 'coroutine'
+
+If you encounter an error message similar to:
+```
+AttributeError: module 'asyncio' has no attribute 'coroutine'. Did you mean: 'coroutines'?
+```
+This usually means that a dependency, often `tenacity` (used by `mega.py`), is an older version that's incompatible with your Python version (typically Python 3.10+).
+
+To fix this, activate your virtual environment and run the following commands to upgrade the libraries:
+
 ```bash
-pyinstaller --name "Kemono Downloader" --onefile --windowed --icon="Kemono.ico" main.py
+pip install --upgrade tenacity
+pip install --upgrade mega.py
 ```
 
-3. Output will be in the `dist/` folder.
