From within HK, how do I find out what threads have new posts (the front page seems to list the 5 latest, but what happens when there are more than that)? And is there a way to mute threads so I don't get notified of any more comments? Right now it seems that all there is are favourites, so that would mean needing to discover that a thread is new, read it, and if I have any passing interest in keeping up to mark it as a favourite and then watching there. But then that would lead to a ton of favourites which won't be usable if they don't sort by latest activity. And tags search the individual emails and don't show a thread overview so I can (ab)use them for that.
Basically how am I supposed to manage the email volume from HK?
