Modern Android devices have quite a bit of RAM, and they allow you to install quite a few applications. It’s not anything special to run 10+ applications at the same time, and switching between them is as easy as pressing the recent apps button. This has some disadvantages, though, as you need to find your app and tap on its name and reopen it.
PIE Controls from Paranoid Android and LMT launcher are some of the most innovative aftermarket features available on Android. Basically, a crescent-shaped menu shows up when you slide your finger from the right or left side of the screen towards the center, and you are able to perform certain actions.
Recently, XDA Senior Member fmaster1 created Loopr to manage your recently opened apps and games in the very same way as PIE. So you can say goodbye to your recent apps button and welcome the new king of task switching. Loopr is customizable, so you can tweak trigger areas, delay, and even crescent color. Another great thing is that it doesn’t require root access, and it works on almost any Android device.
If you like the PIE concept, go to the application thread and give Loopr a try._________
