Folders In Dock
Many complained about Gingerbread's cluttered real estate. So the Android team gave some serious attention to shortcut organization, hence ICSâ€™ ability to store multiple shortcuts into different folders via homescreen or docking tray. Drag an app on top of another and a folder will pop up storing any number of apps you choose to bring over. The folder can then be dropped into the docking tray for instant access when waking the phone.
