EDIT: I mean one outline around the whole board, not an outline around each square
The problem with an outline is that there could be irregular boards (like Omega Chess). The DD suppots this by interpreting a hyphen as a 'hole', in the color of the rim. But the outline would then not follow the boundary of the playing area. So it would be nicer if the light squares are distinguishable from the background.
