Launch any of your apps from any other app!
*MIUI and Android 4.0+ users will need to set the Vertical Location to BOTTOM. Otherwise the drawer's bar will be behind the status bar and will not be accessible.
*On devices with an on-screen navigation bar, you must make sure to pull up from just above the navigation bar when accessing the drawer from the bottom. Otherwise, the navigation bar will intercept the touch event.
Pulling up/down on the left, middle, or right 1/4 of the status bar or bottom of the screen (depending on your setting) will display all of your installed apps. No need to go back to your homescreen to launch other apps!
It will even work when the status bar is not present (e.g. when an app is running in fullscreen). This may interfere with some games so you may want to stop the service before playing games if it causes problems.
There are settings to choose which apps to show or hide in the pulldown and also settings to customize the appearance.
**NOTE: Because of a "feature" of the Android OS, the back and home buttons will not close the app drawer if it is opened within 5 seconds after pressing the home key on your device. Just be aware of that so you don't accidentally close apps behind the drawer.
