-## 🚀 What's New in v3.1.0
+## What's New in v5.0.0?
 
-* **Session Resuming**  
-  * Automatically saves and resumes incomplete downloads.  
+Version 5.0.0 is a major update, introducing comprehensive new features and refining existing ones for a more powerful and streamlined experience:
 
-* **Retry on Failure**  
-  * Failed files auto-retry up to 3 times.  
-  * Clear logging for each retry attempt.
+### ⭐ 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.
 
-* **Batch URL Import**  
-  * Load multiple creator or post URLs from a `.txt` file.  
+### 🎨 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.
 
-* **Improved Manga Mode**  
-  * Better post ordering and handling of missing or untitled posts.  
-  * Optional numeric-only sorting for consistent naming.
+### 🎯 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.
 
-* **UI Enhancements**  
-  * Settings persist across sessions.  
-  * Improved layout spacing, tooltips, and status indicators.
+### 📖 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.
 
-* **Stability & Speed**  
-  * Faster post fetching with lower memory usage.  
-  * Minor bug fixes (duplicate folders, empty post crashes).
+### 🖼️ 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.

-  * Filter by media type: images, videos, or GIFs.  
-  * Skip `.zip` and `.rar` archives.  
+-   **🎯 Filter by Character(s):**
+    -   Enter character names, comma-separated.
+    -   **Syntax Examples:**
+        -   `Tifa, Aerith`: Matches posts/files with "Tifa" OR "Aerith". If "Separate Folders" is on, creates folders "Tifa" and "Aerith". Adds "Tifa", "Aerith" to `Known.txt` separately if new.
+        -   `(Vivi, Ulti, Uta)`: Matches "Vivi" OR "Ulti" OR "Uta". Session folder: "Vivi Ulti Uta". Adds "Vivi", "Ulti", "Uta" to `Known.txt` as separate entries if new.
+        -   `(Boa, Hancock)~`: Matches "Boa" OR "Hancock". Session folder: "Boa Hancock". Adds "Boa Hancock" as a single group entry to `Known.txt` if new (aliases: Boa, Hancock).
+    -   **Filter: [Type] Button (Scope):** Cycles how this filter applies:
+        -   `Filter: Files`: Checks individual filenames. Only matching files from a post are downloaded.
+        -   `Filter: Title`: Checks post titles. All files from a matching post are downloaded.
+        -   `Filter: Both`: Checks post title first. If no match, then checks filenames.
+        -   `Filter: Comments (Beta)`: Checks filenames first. If no file match, then checks post comments. (Uses more API requests).
+-   **🚫 Skip with Words:**
+    -   Enter words (comma-separated) to skip content (e.g., `WIP, sketch`).
+    -   **Scope: [Type] Button:** Cycles how skipping applies:
+        -   `Scope: Files`: Skips individual files by name.
+        -   `Scope: Posts`: Skips entire posts by title.
+        -   `Scope: Both`: Post title first, then filenames.
+-   **✂️ Remove Words from name:**
+    -   Enter words (comma-separated) to remove from downloaded filenames (e.g., `patreon, [HD]`).
+-   **Filter Files (Radio Buttons):**
+    -   `All`: All file types.
+    -   `Images/GIFs`: Common image formats.
+    -   `Videos`: Common video formats.
+    -   `📦 Only Archives`: Exclusively `.zip` and `.rar` files. Disables archive skipping and external link log.
+    -   `🎧 Only Audio`: Common audio formats (MP3, WAV, FLAC, etc.).
+    -   `🔗 Only Links`: Extracts and displays external links from post descriptions. Disables download options.
+-   **Skip .zip / Skip .rar Checkboxes:** Avoid downloading these archive types (disabled if "📦 Only Archives" is active).
 
-* **Manga Mode**  
-  Rename and sort manga posts by title and upload order.  
-  Handles one-image-per-post formats cleanly.
+### Download Customization
 
-* **Image Compression**  
-  Auto-convert large images (>1.5MB) to WebP (requires Pillow).
+-   **Download Thumbnails Only:** Downloads small API preview images.
+    -   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.
 
-* **Multithreaded Downloads**  
-  Adjustable worker count with warnings at unsafe levels.  
-  Full threading for creators, single-thread fallback for post mode.
+### 📖 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.
+    -   `Name: Original File`: All files attempt to keep original names. Optional prefix input appears.
+    -   `Name: Title+G.Num`: All files across posts get post title prefix + global sequential number (e.g., `Chapter 1_001.jpg`). Disables post-level multithreading.
+    -   `Name: Date Based`: Files named sequentially (e.g., `001.jpg`) by post date. Optional prefix input appears. Disables post-level multithreading.
 
-* **Dark Mode**

+### Folder Organization
+
+-   **Separate Folders by Name/Title:** Creates subfolders based on "Filter by Character(s)" or post titles. Uses `Known.txt` as a fallback.
+-   **Subfolder per Post:** If "Separate Folders" is on, creates an additional subfolder for each post.
+-   **`Known.txt` Management (Bottom Left UI):**
+    -   **List:** Displays primary names from `Known.txt`.
+    -   **Add New:** Input field to add new names/groups.
+        -   Simple: `My Series`
+        -   Group (Separate Known.txt): `(Vivi, Ulti, Uta)`

+    -   **Browse... Button:** Select a `cookies.txt` file (Netscape format).
+    -   *Behavior:* Text field takes precedence. If "Use Cookie" is checked and both are empty, tries to load `cookies.txt` from the app directory.
+-   **Use Multithreading Checkbox & Threads Input:**
+    -   *Creator Feeds:* Number of posts to process simultaneously.
+    -   *Single Post URLs:* Number of files to download concurrently.
+-   **Multi-part Download Toggle Button (in log area):**
+    -   `Multi-part: ON`: Enables multi-segment downloads for large files. Can speed up large file downloads but may increase UI choppiness or log spam with many small files.
+    -   `Multi-part: OFF (Default)`: Files downloaded in a single stream.
+    -   Disabled if "🔗 Only Links" or "📦 Only Archives" mode is active.
+
+### Logging & Monitoring
+
+-   **📜 Progress Log / Extracted Links Log:** Main text area for detailed messages or extracted links.
+-   **👁️ / 🙈 Log View Toggle Button:** Switches main log between:
+    -   `👁️ Progress Log`: All download activity, errors, summaries.

+-   **Show External Links in Log Checkbox & Panel:** If checked, a secondary log panel displays external links from post descriptions (disabled in "Only Links" / "Only Archives" modes).
+-   **Export Links Button:** (In "Only Links" mode) Saves extracted links to a `.txt` file.
+-   **Progress Labels:** Display overall post progress and individual file download status/speed.

+    -   Selected posts are added to a download queue.
+-   **Favorite Download Scope Button:** (Next to "Favorite Posts" button)
+    -   `Scope: Selected Location`: All selected favorites download into the main "Download Location". Filters apply globally.
+    -   `Scope: Artist Folders`: A subfolder (named after the artist) is created in the main "Download Location" for each artist. Content goes into their specific subfolder. Filters apply within each artist's folder.

-## 🔧 Backend Enhancements
+## Key Files
 
-* **Session File Support**  
-  Downloads can be resumed even after a crash or restart.  
-  Session progress is saved automatically.
-
-* **Retry Logic**  
-  Auto-retries individual failed files before skipping.  
-  Logs all failures with HTTP codes and reasons.
-
-* **Hash-Based Deduplication**  
-  Prevents redownloading of previously saved files.
-
-* **Smart Naming**  
-  Cleans and standardizes inconsistent post titles.  
-  Adds page indices for manga.
-
-* **Efficient Logging**  
-  Toggle between basic and advanced views.  
-  Live feedback with color-coded logs.
+-   **`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.

-## 📦 Installation
+## Installation
 
 ### Requirements
+-   Python 3.6 or higher
+-   pip (Python package installer)
 
-* Python 3.6+
-* Pip packages:
+### Install Dependencies
+Open your terminal or command prompt and run:
 
 ```bash
 pip install PyQt5 requests Pillow
+```
+
+```bash
+python main.py
+```
+
+
+### 2. Optional Setup
+
+-   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.
+
+---
+
+## Tips & Best Practices
+
+-   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.
+
+---
+
+## Troubleshooting
+
+-   **Downloads not starting?**
+    -   Ensure the download location is set.
+    -   Check your filters aren't too strict.
+    -   If in Favorite Mode, make sure cookie is set and valid.
+
+-   **Missing characters/folders?**
+    -   Review the Missed Character Log.
+    -   Use the "Scan Content for Images" option if image links are embedded in descriptions.
+
+-   **App crashes or logs errors?**
+    -   Check the console/log area for stack traces.
+    -   Run from terminal to capture more error output.
+    -   Ensure `Known.txt` and `creators.json` are valid.
