Being able to hide/show that annoying quick item slot thing that sits right above the attack and skills buttons on screen............

Nothing worse than accidentally tapping that thing and expanding it, obstructing the screen when you are tapping the life out of your mouse when using your skills buttons during intense battles (bad enough we already experience unreal obstruction when some people use their pet's AA and it just hides like everything (enemy/boss pools, for instance) and the accidental tapping on PT members which makes the chat window pop up with the chat options also displayed).......

I know some use the quick item feature heavily but, some only touch it when they do it accidentally.....
