Ok, I've got one. When I use the new multiquote feature, it works like a dream, BUT, after I hit "Quote (5)" or whatever, and make my long post, the "Reply with selected quotes" popup still appears. Ideally, it should disappear after the button is pushed, right? I have to press the trash can icon to get rid of it.
And another "out there" idea that may have been discussed before already... a simple Like button for posts?
