-
-- **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.
-
-- **Multi-language Interface:** Choose from several languages for the UI (English, Japanese, French, Spanish, German, Russian, Korean, Chinese Simplified).
-
-- **Theme Customization:** Selectable Light and Dark themes for user comfort.
-

-
-## ✨ What's New in v6.0.0
-
-This release focuses on providing more granular control over file organization and improving at-a-glance status monitoring.
-
-### New Features
-
-- **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.
-
-- **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.
-
-- **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.
-
-### Bug Fixes
-
-- 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.
-
----
-
-## 📅 Next Update Plans
-
-### 🔖 Post Tag Filtering (Planned for v6.1.0)
-
-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.
-
----
-
-## 💻 Installation
-
-### Requirements
-
-- Python 3.6 or higher
-- pip (Python package installer)
-
-### Install Dependencies
-
-```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
-```
