BUG: Background upload thread was crashing the app
Problem:
- _upload_to_server() runs in daemon thread
- Was directly setting self.player.should_refresh_playlist from thread
- Kivy is NOT thread-safe for direct state modifications
- App crashed after 2-3 minutes during editing
Root cause:
Line 503: self.player.should_refresh_playlist = True
This directly modified Kivy object state from non-main thread
Caused race conditions and memory corruption
Solution:
- Use Clock.schedule_once() to schedule flag update on main thread
- Ensures all Kivy state modifications happen on main thread
- Thread-safe and proper Kivy API usage
- No more app crashes during editing
This was causing the app to crash every 10-20 seconds during edits.
Should now be stable!
