Currently there is only the Map, Token, and GM layer. But what happens when your players want to go invisible? Send the token to the GM layer? but then the player can't see the token. Solution? Player layer visible to only a specific player and GM. When you add a player to your game they get their very own personal layer that the GM can select to send tokens to. Effectively making it Map, Token, GM and (Player name) Layer, (OtherPlayer name) Layer, and (YetAnotherPlayer name) Layer... and so on for each player added to the game. Preferably an optional preference for games that have just too many players to keep track of easily.
