I think you should make options there for things like the set controls, for example I was on the Stealth server earlier and I pressed R to jump, but I brought out my shield, it would be more convenient to be able to set these options in controls .
Also I dunno if this is just me but in spectator mode the camera is locked onto the player and when I try to move it, it locks back to the position behind the player, is the any button we need to hold or?
