Epic Launcher is a KitKat Launcher for devices running Android 4.0+.
The launcher acts as a complete home screen replacement, allowing you to tweak various aspects of Android 4's interface. It lets you customize the desktop, dock, app drawer, and the 'look and feel' of the system (icons and haptic feedback settings). There are plenty of options within Epic Launcher, though it currently doesn't support notification controls.
Epic Launcher comes with a wealth of features, which are updated often.
