Maybe I wasn't clear - not the intent at all to have the DM do the work :)
Concrete example of behavior as of how it works today thru the UI: if a player drops a spell token and then the GM makes that spell token Mask Sensitive, then the player sees the token, but based on the player's LOS. I was hoping that setVisible(nil) would make the token Mask Sensitive and the players would then see it with LOS without needing setVisible(true) similarly as to what can be done in the UI.
