I would love to have the ability to add a token to a door! I love adding extra details to my maps and I want to make it more player friendly. You can do it in a scuffed way with a multi-sided token and place a door on top, but you have to open the door with the light layer, then switch the token display as separate actions. It would be super cool if you could link them together to have the token and the door be synced up.
