Percentage watched completion

It would be nice in the settings for a playlist if you could mark a video as completed at a certain percentage or minutes left. The reason I am requesting this is that when we watch movies with our kids we often get to the last 5 minutes of a movie (credits) and we exit the movie at that point since the kids don’t want to watch the credits.
It would be nice to have the movie marked that is has been fully watched if it is exited at a marker such as, “Once 95% of the time has been watched, auto mark it as completed.”

This is already done like that.
You should only encounter this issue in a few odd cases where the credits take up a considerably large portion of the overall run time of the video.

If you see that there is a large proccentual time left to watch on that video, just jump forwards once or twice.
Otherwise you’ll have to mark the video as ‘watched’ later manually.
