Microsoft has admitted that the lack of a central hub for notifications in Windows Phone 8 is due to the developers running out of time to integrate the feature.
During the Microsoft BUILD event, where the firm announced Windows 8 has sold over four million units, Thomas Fennel admitted the reason behind the lack of a notification center in WP8: "It's very, very important to me… we get tons of feedback from developers that they want something like that as well. I promise we're thinking very, very hard on that one."
Although Microsoft's platform does deliver notifications through its Live Tiles system, notifications for users can't be seen in a central hub. A notification center can also assist users in tracking older notifications that may be lost.
For applications that don't utilize Live Tiles, developers are left without a method of sending its users important notifications.
Microsoft is likely to incorporate the feature in a future build of the just-released Windows Phone 8.
