I could really benefit from bookmarks.
Maybe a long press of a button prompts to allow a tag, as well as skip directly to already tagged points.

I have a 3 year old that will want to see certain scenes from a movie… its disturbing the amount of movies that I know off hand their timestamps for cool scenes.
Being able to set favorite scenes and quickly browse to them has been a long standing feature of disk players. I can’t imagine it would be hard to implement.

Vote it up!!
