- Auto-download new books after each library sync (optional, off by default, Wi-Fi only).
- Batch mode: select multiple books and download them all at once.
- "Stop All" — cancel every download, or every running process, in one tap.
- Cancel a download at any stage — downloading, decrypting, validating, or saving.
- Retry a failed download straight from its notification.
- Cancelling now cleans up partial files and never un-marks an already-downloaded book.
