Yes, this is great, but my users are talking (to me) something like vBulletin works, using an icon to “flag” topics who you have participated in the topic list.
I think you need to better define what you mean by “participate” eg.
read the topic, posted in the topic, liked / invited / Flagged a post in the topic etc.
As it is now, “new” will be for topics in categories you are Watching but have not yet visited. “unread” will be for topics you have read that have since gotten replies you have not yet read.
Does anybody know, why I see My Posts button only after applying filter +https://forum.example.com/posted ?
Is there any way to enable it always on in the top panel?
Also I see only part of topics where I participated (~20) as well as topics that I only assigned them to staff but never posted there.
