If you open the quick menu with your left hand, you can scroll your friends list (and other lists) by pointing the laser at the list and using up/down on the right thumbstick. This is very convenient and way easier than trying to hit the scrollbar accurately or using fling navigation. However, if you open the quick menu with your right hand, your left hand movement inputs override this and cause the menu to close instead. Please allow thumbstick scrolling regardless of which hand opened the quick menu.
