The favorites tab shows "* with blue background" where someone post comments,answer or even accept answer. But when I navigate to that tab, it is hard to know which ones were updated.
The current behavior is kind of confusing because sometimes I do see some updates and sometimes I don't. And so I have to flip through couple of posts and then give up.
Do the posts that were updated move to the top of they stay where they are? If they move to the top, under specific cases or always?
Edit: I have set the sort order: "recent".
As what Hendrik said is the confusion. It is hard to find the post to which a comment was added. Many times I have to leave comment to question to get more clarifications. Then I mark that as favorites to track. Not all users reply/comment in @username format.
