Recently i have been messing around with adb and apk modifications. I noticed i, on my Moto Droid, have Launcher.apk and Launcher2.apk. Launcher2 is the nexus style and Launcher is the drawer. So anyway my friend, on his nexus, only had Launcher2.apk. We adb pulled Launcher.apk from my phone and pushed it to his nexus and it worked. Im not sure if this is said anywhere, looked some and found nothing. Also he noticed an improvement in fluidity.
