-## ✨ What's New in v5.3.0
--   **Multi-Creator Post Fetching & Queuing:**
-    -   The **Creator Selection popup** (🎨 icon) has been significantly enhanced.
-    -   After selecting multiple creators, you can now click a new "**Fetch Posts**" button.
-    -   This will retrieve and display posts from all selected creators in a new view within the popup.
-    -   You can then browse these fetched posts (with search functionality) and select individual posts.
-    -   A new "**Add Selected Posts to Queue**" button allows you to add your chosen posts directly to the main download queue, streamlining the process of gathering content from multiple artists.
-    -   The traditional "**Add Selected to URL**" button is still available if you prefer to populate the main URL field with creator names.
--   **Improved Favorite Download Queue Handling:**
-    -   When items are added to the download queue from the Creator Selection popup, the main URL input field will now display a placeholder message (e.g., "{count} items in queue from popup").
-    -   The queue is now more robustly managed, especially when interacting with the main URL input field after items have been queued from the popup.
+## ✨ 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.

-## ✨ What's New in v5.1.0
--   **Enhanced Error File Management**: The "Error" button now opens a dialog listing files that failed to download. This dialog includes:
-    -   An option to **retry selected** failed downloads.
-    -   A new **"Export URLs to .txt"** button, allowing users to save links of failed downloads either as "URL only" or "URL with details" (including post title, ID, and original filename).
-    -   Fixed a bug where files skipped during retry (due to existing hash match) were not correctly removed from the error list.
--   **Improved UI Stability**: Addressed issues with UI state management to more accurately reflect ongoing download activities (including retries and external link downloads). This prevents the "Cancel" button from becoming inactive prematurely while operations are still running.
+## 📅 Next Update Plans
 
-## ✨ What's New in v5.2.0
--   **Multi-language Support:** The interface now supports multiple languages: English, Japanese, French, Spanish, German, Russian, Korean, and Chinese (Simplified). Select your preferred language in the new Settings dialog.
--   **Theme Selection:** Choose between Light and Dark application themes via the Settings dialog for a personalized viewing experience.
--   **Centralized Settings:** A new Settings dialog (accessible via a settings button, often with a gear icon) provides a dedicated space for language and appearance customizations.
--   **Internal Localization:** Introduced `languages.py` for managing UI translations, streamlining the addition of new languages by contributors.
+### 🔖 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.
