Microsoft Launcher Beta for Android is getting a big update with new features, animations, and other major improvements. The most notable change is the ability to customize the expanded dock. Folders in the app drawer can now be sorted alphabetically and there is also an option in settings that makes it possible to set your own gestures for the folder and app icon. The update is no longer available for Android 4.0.x and 4.1 devices, which means that only newer versions of Android are able to install it.
