Really need to be able to undo image marks and bookmarks set/clear/change. Same for layer colors... (And visibility )

I agree with you. It's been in debate a couple of years ago : should "undo" affect your work only or also affect the timeline (mark image, colour group, etc...).
IMO, any change should be undoable (that's in the to do list).

Yea, I'm with Nathan on this topic. Especially frustrating if you accidentally delete all you image marks and can't recover them.

But I understand that some people don't want to accidentally undo a mark while undoing strokes
Could it be an option? Seems to me the best option
