Control + Z for Op's
Kind of like the Ctrl + Z that makes your Tori do it's previous move, how about a Ctrl + Z for things like accidental Force Specs and Mutes? Say you accidentally spec someone and didn't mean to, you just press ctrl + Z (or another key as this is already binded) and it instantly undo's what you did.
It's only a minor change, but would make things much easier for OP's to organise.
