Default feature request: system wide gesture control

Love paranoid and the direction you are taking.
A feature that I belive many users would benefit from is gesture control when in immersive mode.

For example I am browsing on chrome in immersive mode and I want to access the quick setting tiles in order to change my connection from 3g to wifi. I pull my finger down from the top of the screen to show the notification bar and then repeat to open the quick settings shade. But what's this oh no I have closed the page I was browsing. (This can happen)
My solution to this is a gesture from the side of the screen dragging my finger in a downward arch with a flick at the end to bring down the shade.

Please bring this feature it will really assist with the usability of immersive mode.
