A hovering tray of your favorite apps that follow you around your Android wherever you go. You can long press the control button to stop it or short click to hide it if its in your way at times. When you click an app in your favorites tray it will open. It can be much faster then having to search for it every time or even looking through your history as its sorted alphabetically for convenience.
I personally use it to make quick phone calls.For example, I save the phone app inside the tray, then when in another app an anxious to make a phone call i just pull down my favorites tray i and tap the phone icon. The apps are sorted A-Z to make it easier to search.
