Easier to rotate

Would it be possible for SketchUp for Schools to be able to make it easier to rotate an object? How about being able to insert an angle that you’d like it to rotate (ex. +30 or -45)?

Hello, you can already do that, once you clicked the first time (center of rotation) then picked a reference point with the rotation tool, you can type in the desired angle and validate by hittin enter
