Add option to Custom Filter for Status (Watched/Unwatched)

I’d like to filter for episodes or movies watched prior to X number of days. Currently one can only find stuff that’s been last viewed within X or not within X. Not viewing something within the last X days shows items that have never been watched. It’s confusing but the logic is not quite there yet.

This should do what you’re after.
It lists all movies which

  • are watched at least once
  • were not watched within the last 90 days

If you sort it after the ‘Last viewed’ date, you’ll get the last viewed items first. The reverse is also possible.
