I searched "last watched episode" and not see anything recent.  Back in 2016 add ins and playlists were mentioned.  Neither seamed ideal, but got a lot of posts, so users are certainly interested in this feature being included in "base functionality".  Has any progress been made or should I go with the 2016 suggestions?

There is an addon by @bossanova808 called "checkpreviousepisode" you can install from the repository.

You can also sort your episode listing by Play Count. This will place the first unwatched episode at the top of the list.
