Maybe the fastest way to get to the settings is double swipe down the notifications bar (drag it down with 2 fingers not one), then you'll see all of the toggle settings including air view etc. If you tap and hold on any one of them it will jump straight to the settings of that item.
Some of these new items are quite buried in the motion and gestures. You have to turn the whole group on before getting to another screen with the individuals ones like quick glance, zoom on browser, messages etc separate. They are there but it is a little like getting lost in the forest!
