Is there an app or a way to add pull down power toggles to the Nexus 7? I know that you can pull down on the right side of the screen and get somethings, but I want something more like the Power Toggles app where with one click I can turn off WiFi or cell service. The default only brings you to the Settings to do so. The Power Toggles Widget is nice, but if it is on the screen, I am afraid that I will tap a button by mistake. Thanks!
