As I've mentioned in the ticket, I'm a fan of option 2 since it folds every new feature into ones already in the editor, without adding new ones. I agree about new user visibility however and I believe nowhere is it written that you can press shift to constrain the rotation widget (or unconstrain the new model scale one for that matter). Another button to the top or sidebar could be added, like the one for snapping rotation origin to grid. The amount of buttons is already plenty though, with this change I could happily see the X/Y/Z axis rotate buttons on the sidebars go away and that would free up some space. I still know some people use them, however. Personally I'm leaning towards the rotation and scale dialogue because I have it bound to a shortcut key and I remember it doesn't have a default one. Perhaps putting in a default binding and advertising it as this new dialogue (even though it isn't) where you can input your angles for the rotation widget on release would inform people. As greebo said, please weigh in as it's more or less just me theorizing here. I remember at least two other people mentioning this but I don't remember names. Kingsal, perhaps? Epi? NeonsStyle? I dunno.
