My idea is maybe this can be done like in Blender. In Blender when you Move/scale anything you click the right mouse button, then to set in in place you click the left mouse button to make it final. To put it back and do nothing you click the right Mouse button again and it goes back with no changes. I think that or a varition there of (maybe click left to ajust (or could be both buttons making it work like blender and more (or again lol, left to scale - right to move)), left again to set, and right to do nothing and go back without calculation) would be great when editing in makehuman. It would save waiting for unintended mistakes to calculate and having to undo.
Just a thought
