-## Features
+A powerful, feature-rich GUI application for downloading content from **[Kemono.su](https://kemono.su)** (and its mirrors like kemono.party) and **[Coomer.party](https://coomer.party)** (and its mirrors like coomer.su).
+Built with PyQt5, this tool is designed for users who want deep filtering capabilities, customizable folder structures, efficient downloads, and intelligent automation, all within a modern and user-friendly graphical interface.
 
-* **GUI Interface:** Easy-to-use graphical interface.
-* **URL Support:** Download from a creator's main page (paginated) or a specific post URL from Kemono or Coomer sites.
-* **Download Location:** Select your desired output directory.
-* **Subfolder Organization:**
-    * Organize downloads into folders based on character/artist names found in post titles (using your "Known Names" list).
-    * Option to create a custom folder for single post downloads.
-    * Automatic folder naming based on post title if no known names are matched.

+## What's New in v5.0.0?
+
+Version 5.0.0 is a major update, introducing comprehensive new features and refining existing ones for a more powerful and streamlined experience:
+
+### ⭐ Favorite Mode (Artists & Posts)
+-   **Direct Downloads from Your Kemono.su Favorites:**
+    -   Enable via the "**⭐ Favorite Mode**" checkbox.
+    -   The UI adapts: URL input is replaced, and action buttons change to "**🖼️ Favorite Artists**" and "**📄 Favorite Posts**".
+    -   "**🍪 Use Cookie**" is automatically enabled and required.
+-   **Favorite Artists Dialog:** Fetches and lists your favorited artists. Select one or more to queue for download.
+-   **Favorite Posts Dialog:** Fetches and lists your favorited posts, grouped by artist. Includes search, selection, and known name highlighting in post titles.
+-   **Flexible Download Scopes for Favorites:**
+    -   `Scope: Selected Location`: Downloads all selected favorites into the main "Download Location".
+    -   `Scope: Artist Folders`: Creates a subfolder for each artist within the main "Download Location".
+-   Standard filters (character, skip words, file type) apply to content downloaded via Favorite Mode.
+
+### 🎨 Creator Selection Popup
+-   Click the "**🎨**" button next to the URL input to open the "Creator Selection" dialog.
+-   Loads creators from your `creators.json` file (expected in the app's directory).
+-   Search, select multiple creators, and their names are added to the URL input, comma-separated.
+-   Choose download scope (`Characters` or `Creators`) for items added via this popup, influencing folder structure.
+
+### 🎯 Advanced Character Filtering & `Known.txt` Integration
+-   **Enhanced Filter Syntax:**
+    -   `Nami`: Simple character filter.
+    -   `(Vivi, Ulti, Uta)`: Groups distinct characters into 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)~`: Defines "Boa" and "Hancock" as aliases for the *same character/entity*. 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.
+-   **"Add to Filter" Button (⤵️):** Opens a dialog to select names from your `Known.txt` (with search) and add them to the "Filter by Character(s)" field. Grouped names from `Known.txt` are added with the `~` syntax.
+-   **New Name Confirmation:** When new, unrecognized names/groups are used in the filter, a dialog prompts to add them to `Known.txt` with appropriate formatting.
+
+### 📖 Manga/Comic Mode Enhancements
+-   **"Title+G.Num" Filename Style:** (Post Title + Global Numbering) All files across posts get the post title prefix + a global sequential number (e.g., `Chapter 1_001.jpg`, `Chapter 2_003.jpg`).
+-   **Optional Filename Prefix:** For "Original File" and "Date Based" manga styles, an input field appears to add a custom prefix to filenames.
+
+### 🖼️ Enhanced Image & Content Handling
+-   **"Scan Content for Images":** A checkbox to scan post HTML for `<img>` tags and direct image links, resolving relative paths. Crucial for images embedded in descriptions but not in API attachments.
+    -   When "Download Thumbnails Only" is active, "Scan Content for Images" is auto-enabled, and *only* content-scanned images are downloaded.
+-   **"🎧 Only Audio" Filter Mode:** Dedicated mode to download only common audio formats (MP3, WAV, FLAC, etc.).
+-   **"📦 Only Archives" Filter Mode:** Exclusively downloads `.zip` and `.rar` files.
+
+### ⚙️ UI & Workflow Improvements
+-   **Cookie Management:**
+    -   Directly paste cookie strings.
+    -   Browse and load `cookies.txt` files.
+    -   Automatic fallback to `cookies.txt` in the app directory.
+-   **Multi-part Download Toggle:** Button in the log area to easily switch multi-segment downloads ON/OFF for large files.
+-   **Log View Toggle (👁️ / 🙈):** Switch between the detailed "Progress Log" and the "Missed Character Log" (which now shows intelligently extracted key terms from skipped titles).
+-   **Retry Failed Downloads:** Prompts at the end of a session to retry files that failed with recoverable errors (e.g., IncompleteRead).
+-   **Persistent UI Defaults:** Key filter scopes ("Skip with Words" -> Posts, "Filter by Character(s)" -> Title) now reset to defaults on launch for consistency.
+-   **Refined Onboarding Tour & Help Guide:** Updated guides accessible via the "❓" button.
+

+    -   If "Scan Content for Images" is also active, *only* images found by content scan are downloaded (API thumbnails ignored).
+-   **Scan Content for Images:** Scans post HTML for `<img>` tags and direct image links, resolving relative paths.
+-   **Compress to WebP:** If Pillow is installed, converts images > 1.5MB to WebP if significantly smaller.
+-   **🗄️ Custom Folder Name (Single Post Only):**
+    -   Visible if downloading a single post URL AND "Separate Folders by Name/Title" is enabled.
+    -   Set a custom folder name for that specific post's downloads.
+
+### 📖 Manga/Comic Mode (Creator Feeds Only)
+
+-   **Chronological Processing:** Downloads posts from oldest to newest.
+-   **Page Range Disabled:** All posts are fetched for sorting.
+-   **Filename Style Toggle Button (in log area):**
+    -   `Name: Post Title (Default)`: First file named after post title; subsequent files in the same post keep original names.

+
+---
+
+## Key Files
+
+-   **`Known.txt`:** (Located in the application's directory)
+    -   Stores your list of known shows, characters, or series titles for automatic folder organization.
+    -   **Format:** Each line is an entry.
+        -   Simple: `My Awesome Series`
+        -   Grouped (single `Known.txt` entry, shared folder): `(Boa, Hancock)` - creates folder "Boa Hancock", aliases "Boa", "Hancock".
+    -   Used as a fallback for folder naming if "Separate Folders" is on and no active filter matches.
+-   **`creators.json`:** (Expected in the application's directory)
+    -   Used by the "🎨 Creator Selection Popup".
+    -   A JSON file containing a list of creator objects. Expected structure: `[ [ {creator1_data}, {creator2_data}, ... ] ]` or a flat list `[ {creator1_data}, ... ]`.
+    -   Each creator object should ideally have `name`, `service`, `id`, and optionally `favorited` (integer count for sorting in popup).
+    -   *Example entry in the inner list:* `{"id": "12345", "name": "ArtistName", "service": "patreon", "favorited": 10}`
+-   **`cookies.txt` (Optional):**
+    -   If "Use Cookie" is enabled and no direct string/file is provided, the app looks for this in its directory.
+    -   Must be in Netscape cookie file format.
+-   **Application Settings:** UI preferences (like manga style, multipart preference) are saved by Qt's `QSettings` (location varies by OS). Cookie details and some filter scopes are session-based.

+---
 
-## Configuration
+## Tips & Best Practices
 
-The application saves your list of known names (characters, artists, series, etc.) to a file named `Known.txt` in the same directory as the script (`main.py`). Each name is stored on a new line. You can manually edit this file if needed.
+-   For best results, use **Favorite Mode** if you're a logged-in user with bookmarked artists/posts.
+-   Use **Filter by Character(s)** and keep your `Known.txt` updated to reduce clutter and organize downloads.
+-   Use the **multi-part toggle** for large video/audio files but disable it when downloading large batches of small images to reduce overhead.
+-   Adjust **thread count** based on your internet speed and CPU; too many threads can result in API throttling.
 
-## Dark Theme
+---
 
-The application uses a built-in dark theme for the user interface.
+## Troubleshooting
 
-## Contributing
