I think that player characters that have multiple tokens shouldn't have to manually drag and drop each one from the library or journal, but should be able to add them to the same character sheet in the journal. For example a player in dnd can have their default "human" token, and the dm can right click on the token and select "token 2" for a werewolf transformation or the like. This could also for the dm so they could have more dynamic boss fights with different tokens for a multiple stage boss fight. I could see this coming in handy for both the players and the dm's, so the focus can stay on the game instead of pausing the action or roleplay to find, drag, drop, and transfer stats to a completely new token.
