So, with two tilesets in play, how exactly will this work? Would I be able to make an addition to Tileset #2 AND Tileset #3 one after the other, or would I have to pick between one of them to add to when my turn came up?
Edit: Hmm. I'm not sure if it was Polana or Fubaka, but I'm finding that my palette is extremely limited - in fact, it seems to be limited to only colors currently on the tileset. I'm going to see if I can fix this, but I'm no expert.
Edit: #2: Ah, the old-fashioned "copy-the-whole-thing-into-another-document" trick. Of course.
