-# Kemono Downloader
+# Kemono Downloader v3.1.0
 
-A simple, multi-platform GUI application built with PyQt5 to download content from Kemono.su or Coomer.party creator pages or specific posts, with options for filtering and organizing downloads.
+A feature-rich GUI application built with PyQt5 to download content from [Kemono.su](https://kemono.su) or [Coomer.party](https://coomer.party). Offers robust filtering, smart organization, manga-specific handling, and performance tuning. Now with session resuming, better retry logic, and smarter file management.
 
-## Features
+---
 
-* **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.
-* **Known Names List:** Manage a persistent list of known names (artists, characters, series) for improved folder organization and filtering.
-* **Content Filtering:**
-    * **Character/Name Filter:** Only download posts where the specified known name is found in the title.
-    * **File Type Filter:** Download All Files, Images/GIFs Only, or Videos Only.
-    * **Skip Words Filter:** Specify a list of comma-separated words to skip posts or files if these words appear in their titles or filenames.
-* **Archive Skipping:** Options to skip `.zip` and `.rar` files (enabled by default).
-* **Image Compression:** Optionally compress large images (larger than 1.5MB) to WebP format to save space (requires Pillow library).
-* **Thumbnail Downloading:** Option to download thumbnails. (Note: The previous local API method for enhanced thumbnail fetching has been removed. Thumbnail availability might depend on the source.)
-* **Duplicate Prevention:**
-    * Avoids re-downloading files with the same content hash.
-    * Checks for existing filenames in the target directory.
-* **Multithreading:** Utilizes multithreading for faster downloads from full creator pages (single posts are processed in a single thread).
-* **Progress Log:** View detailed download progress, status messages, and errors.
-* **Dark Theme:** Built-in dark theme for comfortable use.
-* **Download Management:**
-    * Ability to cancel an ongoing download process.
-    * Option to skip the specific file currently being downloaded (in single-thread mode).
-* **Persistent Configuration:** Saves the "Known Names" list to a local file.
+## 🚀 What's New in v3.1.0
 
-## Prerequisites
+* **Session Resuming**  
+  * Automatically saves and resumes incomplete downloads.  
 
-* Python 3.6 or higher
-* `pip` package installer
+* **Retry on Failure**  
+  * Failed files auto-retry up to 3 times.  
+  * Clear logging for each retry attempt.
 
-## Installation
+* **Improved Manga Mode**  
+  * Better post ordering and handling of missing or untitled posts.  
+  * Optional numeric-only sorting for consistent naming.
 
-1.  Clone or download this repository/script to your local machine.
-2.  Navigate to the script's directory in your terminal or command prompt.
-3.  Install the required Python libraries:
-    ```bash
-    pip install PyQt5 requests Pillow
-    ```
-    *(Pillow is required for image compression and potentially for basic image handling.)*
+* **UI Enhancements**  
+  * Settings persist across sessions.  
+  * Improved layout spacing, tooltips, and status indicators.
 
-## How to Run
+* **Stability & Speed**  
+  * Faster post fetching with lower memory usage.  
+  * Minor bug fixes (duplicate folders, empty post crashes).
 
-1.  Make sure you have followed the installation steps.
-2.  Open your terminal or command prompt and navigate to the script's directory.
-3.  Run the script using Python:
-    ```bash
-    python main.py
-    ```
+---
 
-## How to Use
+## 🧩 Core Features
 
-1.  **URL Input:** Enter the URL of the Kemono/Coomer creator page (e.g., `https://kemono.su/patreon/user/12345`) or a specific post (e.g., `https://kemono.su/patreon/user/12345/post/67890`) into the "Kemono Creator/Post URL" field.
-2.  **Download Location:** Use the "Browse" button to select the root directory where you want to save the downloaded content.
-3.  **Custom Folder Name (Single Post Only):** If downloading a single post and "Separate Folders" is enabled, you can specify a custom folder name for that post's content.
-4.  **Filter by Show/Character Name (Optional):** If "Separate Folders" is enabled, enter a name from your "Known Names" list. Only posts with titles matching this name will be downloaded into a folder named accordingly. If empty, the script will try to match any known name or derive a folder name from the post title.
-5.  **Skip Posts/Files with Words:** Enter comma-separated words (e.g., `WIP, sketch, preview`). Posts or files containing these words in their title/filename will be skipped.
-6.  **File Type Filter:**
-    * **All:** Downloads all files.
-    * **Images/GIFs:** Downloads common image formats and GIFs.
-    * **Videos:** Downloads common video formats.
-7.  **Options (Checkboxes):**
-    * **Separate Folders by Name/Title:** Enables creation of subfolders based on known names or post titles. Controls visibility of "Filter by Show/Character Name" and "Custom Folder Name". (Default: On)
-    * **Download Thumbnails Only:** Attempts to download only thumbnails for posts. (Default: Off)
-    * **Skip .zip / Skip .rar:** Prevents downloading of these archive types. (Default: On)
-    * **Compress Large Images (to WebP):** Compresses images larger than 1.5MB. (Default: Off)
-    * **Use Multithreading:** Enables faster downloads for full creator pages. (Default: On)
-8.  **Known Names List:**
-    * The list on the left ("Known Shows/Characters") displays names used for folder organization and filtering. This list is saved in `Known.txt`.
-    * Use the input field below the list and the "➕ Add" button to add new names.
-    * Select names and click "🗑️ Delete Selected" to remove them.
-    * A search bar above the list allows you to filter the displayed names.
-9.  **Start Download:** Click "⬇️ Start Download" to begin.
-10. **Cancel / Skip:**
-    * **❌ Cancel:** Stops the entire download process.
-    * **⏭️ Skip Current File:** (Only in single-thread mode during file download) Skips the currently downloading file and moves to the next.
-11. **Progress Log:** The area on the right shows detailed logs of the download process, including fetched posts, saved files, skips, and errors.
+* **Simple GUI**  
+  Built with PyQt5 for a clean, responsive experience.
 
-## Building an Executable (Optional)
+* **Supports Both Post and Creator URLs**  
+  Download a single post or an entire feed with one click.
 
-You can create a standalone `.exe` file for Windows using `PyInstaller`.
+* **Smart Folder System**  
+  Organize files using post titles, known character/show names, or a folder per post.  
+  Detects and auto-names folders based on custom keywords.
 
-1.  Install PyInstaller: `pip install pyinstaller`
-2.  Obtain an icon file (`.ico`). Place it in the same directory as `main.py`.
-3.  Open your terminal in the script's directory and run:
-    ```bash
-    pyinstaller --name "YourAppName" --onefile --windowed --icon="your_icon.ico" main.py
-    ```
-    Replace `"YourAppName"` with your desired application name and `"your_icon.ico"` with the actual name of your icon file.
-4.  The executable will be found in the `./dist` folder.
+* **Known Names Manager**  
+  Add, search, and delete tags for smarter organization.  
+  Saved to `Known.txt` for reuse.
 
-## Configuration
+* **Advanced Filters**  
+  * Skip posts or files with specific keywords (e.g. `WIP`, `sketch`).  
+  * Filter by media type: images, videos, or GIFs.  
+  * Skip `.zip` and `.rar` archives.  
 
-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.
+* **Manga Mode**  
+  Rename and sort manga posts by title and upload order.  
+  Handles one-image-per-post formats cleanly.
 
-## Dark Theme
+* **Image Compression**  
+  Auto-convert large images (>1.5MB) to WebP (requires Pillow).
 
-The application uses a built-in dark theme for the user interface.
+* **Multithreaded Downloads**  
+  Adjustable worker count with warnings at unsafe levels.  
+  Full threading for creators, single-thread fallback for post mode.
 
-## Contributing
+* **Download Controls**  
+  Cancel files mid-download.  
+  Visual progress tracking with per-post summaries.
+
+* **Dark Mode**  
+  Clean and modern dark-themed interface.
+
+---
+
+## 🔧 Backend Enhancements
+
+* **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.
+
+---
+
+## 📦 Installation
+
+### Requirements
+
+* Python 3.6+
+* Pip packages:
+
+```bash
+pip install PyQt5 requests Pillow
