-## ✨ 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
-```
