 - **Download Speed Limit**: Set your download speed limit in KB/s. This will pass the option `--limit-rate` to yt-dlp.
 - **Throttled Rate Limit**: Restart download if the download speed drops below this value in KB/s. This will pass the option `--throttled-rate` to yt-dlp. Using this option might have a negative effect if you have an unstable or slow internet connection.
 - **Sleep Interval**: Time in seconds to sleep between requests to YouTube. It's a good idea to set this to **3** seconds. Might be necessary to avoid throttling.
+- **Auto Delete Watched Videos**: Automatically delete videos marked as watched after selected days. If activated, checks your videos after download task is finished.
 
 ## Download Format
