Input box for rotation

It would be nice, if you could enter a value into an input box like in a graphics program to rotate a piece. Two boxes would be handy: The first should show the global rotation related to the original position of the piece and the second the number of degrees while you rotate it.

I mean something like this:

I just wanted to ask if you plan to implement something like this in a future version, or if it’s too difficult.

And it would also be cool to have buttons maybe for 10°, 22.5°, 45° and 90° steps or whatever. I think I have seen something like this in Cyberboard.
