Probably not what you’re after OP, but there’s what I do to remember where I left off watching things.

I use a plain text file called watch.txt that I stuck in my home directory. I jot down the name of whatever I was watching, the date, context about the disc/season/episode number, plus the timestamp I stopped at or “done” if I stopped at the end of an episode/disc.

e.g. here’s a snippet from it:

  Evangelion  2026-07-20  Disc 4  29:25
  To Love Ru  2026-06-16  Disc 2  E14 done
  Konosuba    2026-06-27  S2      E01 done

Nothing fancy, but it works for me.
