I’d like to know what’s the point of adding another task here, since it’s same as T37450? Further more, UI design tasks tend to have… bad destiny, often drown in 'forum-like' discussion and then abandoned… :/

Anyway, operator redo (i.e. operator's properties) drawing is (mostly) fully automatic, so even if there may be some space for improvement, I don’t think you can aim at your second suggestion (which would not work in case of narrow panel, too).
