Giving different icons for each situation?
Star = a topic that you liked/favorite.
Bookmark = a topic with bookmarked post.
Hmm… its a good idea indeed. With a limitation to show just 3-5 posts bookmarked, I think, it wouldn’t look too messy.
I had this concept thought before for recommended posts feature. Sometimes a topic has replies from members that adds valuable information to the first post/OP.
A box shows up when you put your mouse (hover) above the bar.
Anyway, I get too excited when I have ideas.
