The operation is very simple, once you install it from Cydia, It can be activated via the settings of your device. The application has three different functions:

• Dock Activation: If enabled, the call of this function will open a curtain to the side of the screen to manage active applications.
• Cycler Activator: If enabled, you can perform a quick switch between applications left in the background.
• Reverse Cycler Activator: performs the same function Cycler Activator, but it performs a reverse rotation.

You can use gestures to activate the functions of this app as well.
