It's been a few years since I've used UBB (6.x), and I just re-started a site running on 7.x. One of the first things I was asked about was "Where is Expanded / Collapsed mode"?
I understand that it was removed from 7.x? How hard would it be to bring it back (either with a pre-existing mod or by writing my own code)? I searched the forums with little success.
