When it comes to scale, rotation, move, there are two display modes:
- One that doesn't show 3D manipulators
- One that shows manipulators.
You are in that second mode, say your are in scale mode, with your scale manipulators visible that you are able to grab, it you hit hotkey R to rotate, you can rotate but it doesn't change the (scale) manipulators to rotation manipulators, to do so you have to click on the button down bellow.
It would be nice that if you hit hotkey G (move), R (rotate), S (scale), it changes the manipulators accordingly. Would this be possible?
