Have "Mark Played on deletion" also add episode Playback History
Enhance the Automatic cleanup function "Mark Played on deletion" to also mark the episode as playback completed or whatever status is needed so that the episode will appear in the Playback History list. Manually deleting the file from the playlist (trash can) pretty much indicates the intention of completeness and desire to let it pass into history.
As it is currently my history is patchy if I skip the credits at the end of episodes. I usually do the skip from my Bluetooth earbuds so the long press Skip is not available.
