One such minor enhancement that Google has introduced in Android 4.4 KitKat is the ability to dismiss upcoming alarms from the notification bar. A notification with the ability to dismiss an upcoming alarm will show up on the notification bar 2 hours before the alarm is ready to go off. This new feature is a part of the new Clock application introduced in Android 4.4, rather than the OS itself. So, if you are too impatient for KitKat, grab the new Android 4.4 DeskClock APK from here. And yes, there are people on this earth who actually wake up before an alarm goes off. I am not one of them though!
