This application is a Xposed Module. It allows you to fine-tune MIUI firmware and its applications. There is a lot of options! You can change the graphical elements, the system behavior when you press the buttons, control music playback by volume buttons, use alt-tab, turn off the screen by doubletap, more finely control the volume, change the desktop grid, fix some firmware errors and much more! Please follow the quick reboot to apply the new tweaks.
The application is designed only for MIUI firmware! It will not work on other firmwares and will not even start. For tweaks require the installation of the module Xposed Framework for MIUI. You can download it here: http://en.miui.com/thread-78894-1-1.html

It is not recommended after flashing to apply app restoring from MIUI backup, because this occurs with errors. If, however, the recovery was done, then return the unit to operation, you must remove it, remove the activator to pump them out of Google Play Store (for free) and apply the settings from the MIUI Tweaks backup recovery methods (menu > settings restore).
