I would like a couple of buttons. 90 degree rotation, -90 degree rotation, and 180 degree rotation. Typically, I type in the value and then hit enter.
While some might complain these buttons are obtrusive, or the same results can be achieved by the control button and mouse dragging, what I would like is to have these and other functions(convert line to shape for example) as buttons in the button palette.
I spend a lot of time arranging my setup to be as efficient as possible for what I do. If these buttons are available, I will make use of them.
