It seems to me that the tokens and the tiles in the game are very similar in nature. Therefore, i think they should probably be grouped together as one in the UI, with a dialog option to choose which one we want.

Also (and this is more important), a lot of times games have many tiles, unlike tokens. However, having to add them one by one is tedious and non-optimized. I think that re-using the same system as the one used for decks would work very well to create a bunch of tiles. So i'd love to see being able to upload one image for whole tilesets and choosing the number of tiles in that image, like it currently works for decks.
