Eventually I will need some additional buttons anyway, to indicate other things than a piece or a hole. E.g. check and win squares for the morph board, evaporate / explode for the capture matrix. 'Blank' could be another button in that group.
AFAICT this getting done, plus a clear way to assign a morph board and/or capture matrix to a piece, would complete the improvements.
