Android: Sidebar is an application switcher that lives on the side of your screen, ready to launch your favourite apps or switch between ones already open with a single swipe. It's fast, flexible, and it lets you customise the apps in the drawer so it's not cluttered with shortcuts you don't need.
Check out the video above to see Sidebar in action. The premise is simple -- just swipe in from the side of the screen to open up Sidebar's app drawer, which displays currently running applications so you can easily switch among them. Hold any icon and drag it out of the sidebar to remove that app. Alternatively, you can toggle over to your favourite apps, and use Sidebar as a quick way to get to the apps you want to use without having to go back to the home screen. Additionally, you can use Sidebar to get quick access to your phone's settings, from Wi-Fi and Bluetooth to rotation, sound and brightness.
Sidebar supports Android phones running Froyo and higher, so if you don't have Ice Cream Sandwich or Jelly Bean's native app switcher, you can get something just as good (if not better). It's free to download, but the $2 pro version lets you add more than eight apps to the sidebar and opens up some additional customisation options.
