There should be a sort option in the watchlist to sort by duration for movies, and [mod-edit: duplicate, see below] episode count for shows. Obviously if you have the filter set to “Movies & Shows” you would not have this sort option, but when filtered to just one type this option would be available.
Just some housekeeping… there’s already an existing suggestion discussing an option to sort the watchlist by duration.
Please comment/vote for that particular aspect of your suggestion in that thread in order to help us avoid distracting or cannibalizing votes.
