Well they could make a better GUI. Like open the hack and you have buttons saying : Assault Rifles, Secondarys, Specials, Launchers etc. and when you click on them the menu changes to the guns with the hotkeys and when you press the key it will unlock the camo and then have a back key or something and then go into a different category and press the keys there. I make it sound complicating but basically something similar to THIS
