I just saw a neat, cool feature come and go in a flash. In "New Posts", just for a moment, to the left of each topic was a link to "View First Unread". This popped up as I was "opening links in a new tab" in Firefox. When I saw it I said, "Cool!" and in my enthusiasm to test it out, unintentionally closed the New Posts tab and it was gone. Going back got me the same old, same old.
I WANT THAT FEATURE!
