Heads Up! - notifications - Android Apps on Google Play. Some of the coming Android L features are already being ported to current phones by developers. This one takes the excellent Google Notifications bar on the top of Android phones, and brings the Notifications you choose front and center, in floating bars on top of the screen. You can tweak the ones you want, or turn them off altogether. I already have my notifications going to my SmartWatch, where it gently vibrates to let me know; but, this looks like another good way to keep up with my day.
