I find myself having to click and unclick the 'set pivot' checkbox in the Move/Copy dialogue box as I move components around. I seem to do this at least once per use of the Move/Copy tool. Having a keyboard shortcut (say 'spacebar') to toggle this checkbox would be very handy and cut down on required mouse movements. The 'spacebar' shortcut would make the Move/Copy tool work a lot more like IronCAD's TriBall tool.
Also, it would be *very* useful to have the Move/Copy tool remember it's last position on a given Component/Body/whatever. It is quite annoying to have to reorient the Move/Copy tool every time I want to move and remove a component.
Lastly, adding a 'ctrl' press and hold shortcut when moving to automatically enable copy, would also be very handy.
