That your conversation is more similar to my another suggestion, but my suggestion is more comprehensive and completed:
It’s hard to display at 1 Timeline at once all 4 useful types of marks: My posts, Reply posts, Search results, FAQ answers. To do this you will need to add a switcher or display Search results and FAQ answers a little to the side or just display 4 timelines - one for each type of posts.
Yep! I’ve just devise the world best solution for so many marks at 1 timeline without any switchers etc. Message me when you will need it.
