iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Apple Has Hired MobileNotifier Developer Peter Hajas
Now, there's a hot tweak called MobileNotifier (beta 3 release) via Cydia that makes notifications unobtrusive and allows you to keep using existing apps. An elegant bar appears up top of your homescreen and with one tap you can choose to close or open the notification. Alerts will also appear on your lockscreen. When you double tap the Home button, you'll see a list of your recent alerts via the AlertDashboard.And associated video:
Peter Hajas doesn't come right out and say that he's now working Apple but did post a cryptic update to his blog saying that he will be taking a break from MobileNotifier for a while due to other opportunities.
RedmondPie has since discovered a (now deleted) Tweet posted in early May by Hajas saying that he would be heading off to work in California at a "fruit" company. Meanwhile, we've also independently confirmed that Hajas is now an employee at Apple.
Apple is rumored to be improving iOS's notification system in the next version of iOS to be detailed at WWDC, and a report from mid-February had indicated that Apple was hiring an unnamed outside developer to revamp notifications, although it is unknown if that person was indeed Hajas. Regardless, Apple has certainly already worked heavily on such a system prior to this hire, but it's still interesting nonetheless.
