What I would like to see is a way to link tokens to the characters you assign players.
This could either be by assigning a token to the character directly and you could then drop that into each map. Or by allowing you to link the token to a character that has been created.
Once linked a token would maintain all stat changes with the character, such that any other linked tokens on other maps would also be updated.
This would allow DMs to setup the PCs in the starting area of each map and have their stats updated automatically on map change.
