Hi AgentTheGreat, firstly, great work!
I wonder if you want your Notification Centre to be accessible within an app? My only concern is, if so then the swipe gesture would need to start from the left edge of the screen. Personally I think this gesture should be saved for switching between apps just like what you do with WinRT tablets.
I'd like to hear your thoughts on this. Thanks!
Firstly, thanks very much!
As I said before, I don't think the notification center needs to be accessible from anywhere other than the home screen because Windows Phone supports toast messages that tell you the whole story when you are within an app. Swiping on a toast message to get to the notification center might be a good idea though -- as one of the guys pointed out above.
About the task switching: I think that is more feasible on a rather large tablet but on a 4 or 5 inch phone I think swiping from edges when you are in an app would create some major issues, because swiping gestures that are expected to be registered by the app for scrolling, for example, would get confused by the system as app switching gestures. You can imagine how frustrating that can become! Now adding a 'charms' bar to the top of the UI would work well, because the gesture is unlikely to get registered as something else.
