iOS Notification Center Concept
Notification Center in its current form is visually quite pleasing but isn't as powerful as it could be. My concept uses the current UI but makes it more powerful by taking usual actions right from the Notification Center without opening apps.
How it works:
Swiping left on a notification brings up a set of options that would usually have to be done by opening relevant apps and could take 2-3 steps. This works with all notifications. Apps from the App store can take advantage of this too. For example: A Facebook notification can be commented on, liked, or shared right from the Notification Center.
