[Concept] Notification toggles
Many people were disappointed at how there are still no toggles in iOS. Here is a very crude mockup which wouldn't even need a separate interface to add toggles. You could long press any settings icon and a little portion of the Notification Center would slide down allowing you to drag toggles up there. In true Apple fashion, you would only be able to put 4 toggles there :P
By the way, how does one insert large images into a post?
