I still cant understand why the had to make the action center a swipe down instead of a swipe from the left.
Swiping down compleeeetly contradicts the wp8 design language. Never ever has there anything to swipe down from. A beatiful google now like/notification/shortcut area could have easily added left from the home screen.
That would have made the experience so much more consistent. Now its just a boring rip-offs of how androids and ios do it for years. Feels uninspired and rushed.
Still... better this than no notificiation center
because the action centre it can be open while you are using apps, and swipe from left is already used by other apps
