- Optimize scanning so playouts are only rebuilt when necessary (duration changes, or collection membership changes)
- Automatically add new posters during scanning
- Support more poster file types (jpg, jpeg, png, gif, tbn)
- Add "Refresh All Metadata" button to media sources page; this should only be needed if NFO metadata or posters are modified
- Add progress indicator for media sources that are being actively scanned
- Prevent deleting media source during scan
- Prevent creating playout with empty schedule
