I would love if you could see which comments were read/unread directly on the frames! As well as a sneak peak of some of the conversation as an option directly on screen vs only in sidebar.
I would also love as a filtering option in the sidebar if you could filter to only show comments or comments related to that specific frame and another filtering option to see that specific section.
I think the comments section can be improved since my team often gets lost in them and ends up messaging in slack which I find hard to track and make edits this way. Would love if a tips bar popped up for new users to teach them how to use the comments and how to filter etc since the filtering is a little hidden. Wish the filtering was and sorting was less hidden!
