Another thing, with the bounding box enable,
it's not possible to move the objects selected by it "center" (same than the pivot of rotation)?
Maybe by an arrow middle bottom box (like up arrow rotation) so the middle pivot of move will be visible and moving the box by this move pivot will be easy?
Actually we can see only one middle of the box in moving if we pick the larger middle side or hight middle side
and pivot is invisible and we must make 2 moves! ;)
