What he is saying, ***I THINK***, is that you can't do that if the menus get glitched up.
IMO a redundancy is not necessarily a bad idea.
I am also strongly in support of the idea of adding a VIP/Admin mute/gag function.
I know, "but why can't you mute him?" - if you're playing no ZS, but TTT for example and the guy is an annoying guy who also happens to do false call outs, then such a function is more useful as if only you have that player muted, he can still false call out, but if he is gagged, he loses that ability.
