Just when you thought we were running out of tweaks that could be done to Ice Cream Sandwich on the Galaxy Nexus, the folks behind AOKP have something new to show: custom navigations buttons. Since the G-Nex sports on-screen buttons, developers have realized that this area could be used for more than back, menu, search and home. What if you added a shortcut to your most-used app, like say the browser? Or maybe you need to text or pop up the camera at a moment’s notice? You will be able to, very soon.
