My suggestion is simple, allow players to use the /emas command to allow players who use multiple characters (Such as a character and their cohort, in D&D) to activate token actions as the individual characters. This will avoid the players needing to swap who they are (in the "As:" dropdown menu) every time they need to make an action. Currently the command is GM use only, and it allows the gm to act in character, and I assume is one of the more used commands (Knowing the number of times our GM talks as our enemies/allies).. I suggest either make a setting for the players, or if its easier, do something like "/eas" or "/emas1" where 1 is the first person in the dropdown menu. Or you could have "/emasNAME" and do a check to see if the name matches with allowed player names.
