Analyses videos in your library based on audio. For example if there are two or more episodes of a season in your library, checks for the same audio match within the first 20 minutes of the episode between episodes and marks their timestamps. While watching an episode it gives you the Skip Intro button similar to Netflix/Apple TV etc.

Somewhat in a similar way the skip end credits works (for example allows you to skip credits in Marvel movies to post / mid credit scenes)
