Is just to port the "/plot toggle explosions", "/plot toggle pvp", "/plot toggle fire" and "/plot toggle mobs" toggle commands to quarters, so you could do "/q toggle explotions", "/q toggle pvp" or "/q toggle fire" just as you do with towns or plots. Mainly to set up underground fighting clubs or explosion/fire/mob griefing testings chambers for laboratory-esque roleplay (Example: Testing Stationary Turrets with different cannon types, and using a quarter with explosions toggled on as a sort of griefable target)
