The update also brings new features to the app that might interest you: It now supports slide2lock, touch2wake, and doubletap2wake. These features are normally found within several custom kernels, but now it’s built into an app that is capable of working on basically any kernel that is close enough to the stock kernel.
In order to use the app’s features, you must be running a rooted Galaxy Nexus, Nexus 4, or Nexus 7 (2013). You may also need to flash to a different kernel if your current kernel is not yet supported.

this might bring some drain, some users report quite a big battery drain some not, I will address this issue in some time. Check yourself how much an issue it is for you.
