I know this is probably working by design, but I like to use the "What's New?" button to see a list of new threads. Though if I read a thread it disappears from the listing understandably because it no longer has any new posts. That makes it hard to go back into the the thread as you have to go into the subforum and find it.
Is there a function that will show threads by last post in order even if the thread has been read? Maybe the thread title would be lighter to designate already read.
Question for you... do you see that link on your forum? I found that link here on xenforo.com but I can't seem to find it on my test forum. I can't even find a phrase for it when I search for "All Recent Messages". It might only be implemented here on xenforo.com for the time being, perhaps slated for beta 3.
