Had an idea as I was making a character with a werewolf theme. When they turn, they have the option to "flip" the token over, to show the werewolf icon or any other icon they choose! Applicable for tokens that like to wear cloaks or wear disguises and drop as they choose. Or have a "in combat" token vs "out of combat" token. Or have a plot twist and the npc guide is actually the villain and turns into an evil token! Magic item's token is reacting. That chest was actually a mimic! Much easier than the DM having to drag tokens in an out and just helps keep track what active effects or appearance that token has. EDIT: And players could have control as well if the GM allows on whatever tokens. What do you guys think?
