The transparent status bar in Kit Kat has to be one of the coolest features. Before this we were stuck with a solid black bar. Of course the new transparent status bar looks much more sleek. Thanks to a new Xposed Framework module by developer "Woalk" you are now able to change your status bar transparency style. The module features eight different styles. Styles include Android L, HTC Sense 5, Stock Kit Kat, and more. This mod does require that you be running an AOSP rom. So this should work with nexus device on the stock build or any device running a CM style rom. Head to the link below for the download.
