1. The UI for choosing which face type to perform some operators on. I had a numeric input field which is fairly unfriendly in hindsight. 2. I didn't have twist, elongate or several of your other operations. They won't always make sense as general operations but it's given me some ideas. 3. Lots of little UI touches. I was fumbling around with various UI ideas and you've given me a better sense of direction.
