Allow players to update their own default token (just the image - not the settings). Twice now, I've had issues that I could not fix as a player because I can't change the default token. The first time, a GM accidentally assigned different images to my avatar and default token (I eventually had to get another GM to correct this). This time, the avatar and default token images disappeared from my character (replaced with the little "file not found" indicator) in both an upcoming game and my character vault - I could reupload the avatar image but the default token is still the error indicator (which is no token so I can't drag my char onto a map or anything).
