In theory, ability to use the rotation gizmo in Python.
If we could use the gizmo to rotate local and world it would allow advanced rotations with little code.
Image show a plane that we want to rotate via the green axis. Currently this is very hard to code and the coder need extended knowledge of 3D math.
But with a feature like rotate_gizmo("x",0.1,"local") would simplify a lot.
