That raises the problem for how to indicate participating pieces that are not present in the initial setup. Perhaps I should add a button for that, "Starts off board", so that one could select a piece type in the table, and then press that button instead of selecting a board square. These piece types would then also be left in the table when you press the "Start position" button.
Would it be possible to have it so that you can switch back and forth between playtesting and editing?
