A recent patent application from Apple reveals that the company is considering adding a proper "At a Glance" notification screen for the iPhone. The proposed screen would allow users to quickly jump to the desired notification simply by pressing on the corresponding notification.

At present, the iPhone's notification lists is a list that disappears when the phone is unlocked. This sort of notification system may become more important once 3rd party "push" notifications are activated, as the number and variety of these notifications will likely increase significantly.
