What a pain it is, to finish a layout, and then realize you need it just a bit to the right or left. We have a long process of tearing it down bit by bit, just to move it over a tiny bit.
Or perhaps we realize our base would be better off if it were flush to one side of the grid...
This would all be so much easier if we could "select all" and drag everything at once.
What do you think?
