The first thing I do when I come onto the forum is go to Unread and then filter by replies to see anything that is unanswered. Next thing I do is look for things that have at least one answer but is still unresolved. I am wondering whether an extra tab for “Unresolved” items would be good. Within that you could also split between unanswered (i.e. no reply at all) and unresolved…
Also, would be good to clear out/resolve some of the older items. Especially the unread ones.
