Oops I forgot to mention this has a quick buying system
quickbuy MenuID Slot
example:
quickbuy 2 1 // this would buy Shotgun M3
So you could bind a key: bind z "quickbuy 2 1"
I do plan on making up a rebuy and autobuy system in the future, I might get it done for 1.1 but I'm currently working on enhancements.
