- Collapsible per-file progress list — file name, size, and individual download progress bar
- ETA, total size, and upload ratio on each card (e.g. `151.7 MB / 263.6 MB • ETA 27s • ratio 0.42`)
- Sequential download + in-app ExoPlayer — tap Play (≥ 5 % downloaded) to watch before the file is complete; position is remembered across sessions and cleared when the torrent is deleted
+- Multi-language subtitle support — automatically detects `.srt` files and provides a language selector in the player UI
- Pause, resume, and delete torrents (with optional file removal)
- Persistent sessions — resume data is saved on `onStop` and restored on next launch
- Share `.torrent` files to other clients via the system share sheet
