Is is possible to make the buttons for the coins cycle through three states instead of just two? So default is "empty", first click "filled", then second click "X", and next click back to default. This is simply relating to using coins for the expansion. We've been "unselecting" them from the left when using them, and this usually works ok, but if we ever use up all we have, we need to use a token of some sort to remember how far along the track we've come. Would be nice with a built in way to avoid that. Not sure if there are built in buttons for this, but making custom ones with three different states shouldn't be too hard, but up to you if you think it's worth the work :)
