-# Kemono Downloader - Detailed Feature Guide
-
-This guide provides a comprehensive overview of all user interface elements, input fields, buttons, popups, and functionalities available in the Kemono Downloader.
-
----
-
-## Main Interface & Workflow
-
-These are the primary controls you'll interact with to initiate and manage downloads.
-
-### 1. Main Inputs
-
--   **🔗 Kemono Creator/Post URL Input Field:**
-    -   **Purpose:** This is where you paste the URL of the content you want to download.
-    -   **Usage:** Supports full URLs for:
-        -   Kemono.su (and mirrors like kemono.party) creator pages (e.g., `https://kemono.su/patreon/user/12345`).
-        -   Kemono.su (and mirrors) individual posts (e.g., `https://kemono.su/patreon/user/12345/post/98765`).
-        -   Coomer.party (and mirrors like coomer.su) creator pages.
-        -   Coomer.party (and mirrors) individual posts.
-    -   **Note:** When **⭐ Favorite Mode** is active, this field is disabled and shows a "Favorite Mode active" message.
-
--   **🎨 Creator Selection Button:**
-    -   **Icon:** 🎨 (Artist Palette)
-    -   **Location:** Next to the URL input field.
-    -   **Purpose:** Opens the "Creator Selection" dialog to easily add multiple creators to the URL field.
-    -   **Dialog Features:**
-        -   Loads creators from your `creators.json` file (expected in the app's directory).
-        -   **Search Bar:** Filter the list of creators by name.
-        -   **Creator List:** Displays creators with their service (e.g., Patreon, Fanbox) and ID.
-        -   **Selection:** Checkboxes to select one or more creators.
-        -   **"Add Selected to URL" Button:** Adds the names of selected creators to the URL input field, comma-separated.
-        -   **"Download Scope" Radio Buttons (`Characters` / `Creators`):** Determines the folder structure for items added via this popup.
-            -   `Characters`: Assumes creator names are character names for folder organization.
-            -   `Creators`: Uses the actual creator names for folder organization.
-
--   **Page Range (Start to End) Input Fields:**
-    -   **Purpose:** For creator URLs, specify a range of pages to fetch and process.
-    -   **Usage:** Enter the starting page number in the first field and the ending page number in the second.
-    -   **Behavior:**
-        -   If left blank, all pages for the creator are typically processed (or up to a reasonable limit).
-        -   Disabled for single post URLs or when **📖 Manga/Comic Mode** is active (as manga mode fetches all posts for chronological sorting).
-
--   **📁 Download Location Input Field & Browse Button:**
-    -   **Purpose:** Specify the main directory where all downloaded files and folders will be saved.
-    -   **Usage:**
-        -   Type or paste the path directly into the field.
-        -   Click the **"Browse..."** button to open a system dialog to select a folder.
-    -   **Requirement:** This field must be filled unless you are using the "🔗 Only Links" filter mode.
-
-### 2. Action Buttons
-
--   **⬇️ Start Download / 🔗 Extract Links Button:**
-    -   **Purpose:** The primary action button to begin the downloading or link extraction process based on current settings.
-    -   **Behavior:**
-        -   If "🔗 Only Links" filter is selected, the button text changes to **"🔗 Extract Links"** and it will only gather external links from posts.
-        -   Otherwise, it reads **"⬇️ Start Download"** and initiates the content download.
-
--   **⏸️ Pause / ▶️ Resume Download Button:**
-    -   **Purpose:** Temporarily halt or continue the ongoing download/extraction process.
-    -   **Behavior:**
-        -   When active, the button shows **"⏸️ Pause Download"**. Clicking it pauses the operation.
-        -   When paused, the button shows **"▶️ Resume Download"**. Clicking it resumes from where it left off.
-        -   Some UI settings can be changed while paused (e.g., filter adjustments), which will apply upon resuming.
-
--   **❌ Cancel & Reset UI Button:**
-    -   **Purpose:** Immediately stops the current download/extraction operation and performs a "soft" reset of the UI.
-    -   **Behavior:**
-        -   Halts all active threads and processes.
-        -   Clears progress information and logs.
-        -   Preserves the content of the "🔗 Kemono Creator/Post URL" and "📁 Download Location" input fields. Other settings are reset to their defaults.
-
--   **🔄 Reset Button (located in the log area):**
-    -   **Purpose:** Performs a "hard" reset of the UI when no operation is active.
-    -   **Behavior:**
-        -   Clears all input fields (including URL and Download Location).
-        -   Resets all filter settings and options to their default values.
-        -   Clears the log area.
-
----
-
-## Filtering & Content Selection
-
-These options allow you to precisely control what content is downloaded or skipped.
-
--   **🎯 Filter by Character(s) Input Field:**
-    -   **Purpose:** Download content related to specific characters.
-    -   **Usage:** Enter character names, comma-separated.
-    -   **Advanced Syntax:**
-        -   `Nami`: Simple character filter. Matches "Nami".
-        -   `(Vivi, Ulti, Uta)`: Grouped characters. Matches "Vivi" OR "Ulti" OR "Uta". If "Separate Folders" is on, creates a shared folder for the session (e.g., "Vivi Ulti Uta"). Adds "Vivi", "Ulti", "Uta" as *separate* entries to `Known.txt` if new.
-        -   `(Boa, Hancock)~`: Aliased characters. Matches "Boa" OR "Hancock" but treats them as the same entity. If "Separate Folders" is on, creates a shared folder (e.g., "Boa Hancock"). Adds "Boa Hancock" as a *single group entry* to `Known.txt` if new, with "Boa" and "Hancock" as its aliases.
-
--   **Filter: [Type] Button (Scope for Character Filter):**
-    -   **Location:** Next to the "Filter by Character(s)" input.
-    -   **Purpose:** Defines how the character filter is applied. Cycles through options on click.

-## Download Customization
-
-Options to further refine the download process and output.
-
--   **Download Thumbnails Only Checkbox:**
-    -   **Purpose:** Download only the small preview images (thumbnails) provided by the API, instead of full-resolution files.
-    -   **Behavior:** If "**Scan Content for Images**" is also active, this option's behavior changes: *only* images found by the content scan (embedded `<img>` tags) are downloaded as thumbnails (API thumbnails are ignored).
-
--   **Scan Content for Images Checkbox:**
-    -   **Purpose:** Actively scan the HTML content of posts for `<img>` tags and direct image links. This is crucial for downloading images embedded in post descriptions that are not listed as direct attachments in the API response.
-    -   **Behavior:** Resolves relative image paths to absolute URLs for downloading.
-
--   **Compress to WebP Checkbox:**
-    -   **Purpose:** Convert downloaded images to WebP format to potentially save disk space.
-    -   **Requirement:** Requires the `Pillow` library to be installed.

-        2.  The "**Separate Folders by Name/Title**" option is enabled.
-
----
-
-## 📖 Manga/Comic Mode
-
-Specialized mode for downloading creator feeds in a way suitable for sequential reading, like manga or comics. This mode is implicitly active when downloading from a creator URL and certain filename styles are chosen.
-
--   **Activation:** Primarily by downloading a creator's feed (not a single post) and selecting a relevant "Filename Style".
--   **Core Behavior:** Processes and downloads posts from the creator's feed in chronological order (oldest to newest). The "Page Range" input is typically disabled as all posts are fetched for correct sorting.
-
--   **Filename Style Toggle Button (located in the log area):**
-    -   **Purpose:** Controls how files are named when downloading in a manga/comic-like fashion. Cycles through options on click.
-    -   **Options:**
-        -   `Name: Post Title` (Default for non-manga): The first file in a post is named after the post title; subsequent files in the *same post* keep their original names.
-        -   `Name: Original File`: All downloaded files attempt to keep their original filenames as provided by the server. An optional "Filename Prefix" input field appears.
-        -   `Name: Title+G.Num`: (Global Numbering) All files across all downloaded posts for the creator get a prefix from their respective post's title, followed by a global sequential number (e.g., `Chapter 1_001.jpg`, `Chapter 1_002.jpg`, `Chapter 2_003.jpg`). This ensures strict order across posts. Disables post-level multithreading for sequential numbering.
-        -   `Name: Date Based`: Files are named sequentially (e.g., `001.jpg`, `002.jpg`) based on the post's publication date. An optional "Filename Prefix" input field appears. Disables post-level multithreading.
-
--   **Optional Filename Prefix Input Field (Manga Mode):**
-    -   **Visibility:** Appears when "Filename Style" is set to `Name: Original File` or `Name: Date Based`.
-    -   **Purpose:** Allows you to add a custom prefix to all filenames generated using these styles (e.g., `MySeries_001.jpg`).
-

-
--   **Separate Folders by Name/Title Checkbox:**
-    -   **Purpose:** Creates subfolders within the main "Download Location" based on matching criteria.
-    -   **Behavior:**
-        -   If "**Filter by Character(s)**" is used, folders are named after the matched character(s)/group(s).
-        -   If no character filter matches (or no filter is active), but the post title matches an entry in `Known.txt`, a folder named after the `Known.txt` entry is created.
-        -   If neither of the above, and this option is checked, folders might be created based on post titles directly (behavior can vary).
-
--   **Subfolder per Post Checkbox:**
-    -   **Purpose:** Creates an additional layer of subfolders, where each individual post's content goes into its own subfolder.
-    -   **Behavior:** Only active if "**Separate Folders by Name/Title**" is also checked. The post subfolder will be created *inside* the character/title folder. Folder names are typically derived from sanitized post titles or IDs.
-
--   **`Known.txt` Management UI (Bottom Left of UI):**
-    -   **Purpose:** Manages a local list (`Known.txt` file in the app directory) of series, characters, or general terms used for automatic folder organization and character filter suggestions.

-        -   **Add New Input Field:** Enter a new name or group to add to `Known.txt`.
-            -   Simple Name: e.g., `My Series`
-            -   Group (creates separate entries in `Known.txt`): e.g., `(Vivi, Ulti, Uta)`
-            -   Group with Aliases (single entry in `Known.txt` with `~`): e.g., `(Boa, Hancock)~`
-        -   **➕ Add Button:** Adds the entry from the "Add New" field to `Known.txt` and refreshes the list.
-        -   **⤵️ Add to Filter Button:** Opens a dialog displaying all entries from `Known.txt` (with a search bar). Select one or more entries to add them to the "**🎯 Filter by Character(s)**" input field. Grouped names from `Known.txt` are added with the `~` syntax if applicable.

+  <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>

+<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>

+# 🛠️ 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.

-## Feature Overview
-
-Kemono Downloader offers a range of features to streamline your content downloading experience:
-
--   **User-Friendly Interface:** A modern PyQt5 GUI for easy navigation and operation.
--   **Flexible Downloading:**
-    -   Download content from Kemono.su (and mirrors) and Coomer.party (and mirrors).
-    -   Supports creator pages (with page range selection) and individual post URLs.
-    -   Standard download controls: Start, Pause, Resume, and Cancel.
--   **Powerful Filtering:**
-    -   **Character Filtering:** Filter content by character names. Supports simple comma-separated names and grouped names for shared folders.
-    -   **Keyword Skipping:** Skip posts or files based on specified keywords.
-    -   **Filename Cleaning:** Remove unwanted words or phrases from downloaded filenames.
-    -   **File Type Selection:** Choose to download all files, or limit to images/GIFs, videos, audio, or archives. Can also extract external links only.
--   **Customizable Downloads:**
-    -   **Thumbnails Only:** Option to download only small preview images.
-    -   **Content Scanning:** Scan post HTML for `<img>` tags and direct image links, useful for images embedded in descriptions.
-    -   **WebP Conversion:** Convert images to WebP format for smaller file sizes (requires Pillow library).
--   **Organized Output:**
-    -   **Automatic Subfolders:** Create subfolders based on character names (from filters or `Known.txt`) or post titles.
-    -   **Per-Post Subfolders:** Option to create an additional subfolder for each individual post.
--   **Manga/Comic Mode:**
-    -   Downloads posts from a creator's feed in chronological order (oldest to newest).
-    -   Offers various filename styling options for sequential reading (e.g., post title, original name, global numbering).
--   **⭐ Favorite Mode:**
-    -   Directly download from your favorited artists and posts on Kemono.su.
-    -   Requires a valid cookie and adapts the UI for easy selection from your favorites.
-    -   Supports downloading into a single location or artist-specific subfolders.
--   **Performance & Advanced Options:**
-    -   **Cookie Support:** Use cookies (paste string or load from `cookies.txt`) to access restricted content.
-    -   **Multithreading:** Configure the number of simultaneous downloads/post processing threads for improved speed.
--   **Logging:**
-    -   A detailed progress log displays download activity, errors, and summaries.
-
----
-
-## ✨ What's New in v5.1.0
--   **Enhanced Error File Management**: The "Error" button now opens a dialog listing files that failed to download. This dialog includes:
-    -   An option to **retry selected** failed downloads.
-    -   A new **"Export URLs to .txt"** button, allowing users to save links of failed downloads either as "URL only" or "URL with details" (including post title, ID, and original filename).
-    -   Fixed a bug where files skipped during retry (due to existing hash match) were not correctly removed from the error list.
--   **Improved UI Stability**: Addressed issues with UI state management to more accurately reflect ongoing download activities (including retries and external link downloads). This prevents the "Cancel" button from becoming inactive prematurely while operations are still running.
----
-
-## Installation
-
-### Requirements
--   Python 3.6 or higher
--   pip (Python package installer)
-
-### Install Dependencies
-Open your terminal or command prompt and run:
-
-```bash
-pip install PyQt5 requests Pillow mega.py
-```
-
-### Running the Application
-Navigate to the application's directory in your terminal and run:
-```bash
-python main.py
-```
-
-### Optional Setup
--   **Main Inputs:**
--   Place your `cookies.txt` in the root directory (if using cookies).
--   Prepare your `Known.txt` and `creators.json` in the same directory for advanced filtering and selection features.

-## 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
-pip install --upgrade tenacity
-pip install --upgrade mega.py
-```
