The move/rotate tool should always be displayed automatically on screen, even if you zoom in on an object.
The problem: If you zoom in on an object to see a small section of it, you cannot immediately move or rotate it in this view because the move/rotate tool is not displayed in this view. Instead, you first have to zoom out, then move the move/rotate tool to the area you were looking at in detail, then zoom in again and only then can you use the move/rotate tool in the detail view. This is terribly cumbersome and slows down the work process unnecessarily.
