This is an Pro Extension to Xposed Additions which will add more features to the module. With the additional Double Click and Multi Key Event support provided by this extension, you will be able to assign 6 different actions per key in each screen state, which mean all-in-all 12 different actions on one single button. Since most newer devices only have Power and two Volume buttons, this extension will help you get more out of your buttons. 3 buttons can contain 36 different actions.
