Toggling effects #54
Description
chain.disable and chain.enable are nice, but if you want the player to be able to enable or disable effects, you have to do the bookkeeping yourself in the game to keep track of the current status.
It'd be great if there was a chain.toggle, which disabled the effects if they were enabled, and vice versa.
Failing that, is there a way to check if an effect currently is enabled?
