+                -   **Informative Text:** "Would you like to restart the application now?"
+                -   **Buttons:** "Restart Now", "OK" (or similar to defer restart).

     -   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.
