Hey, so I am going to leave a link to developers that manage to get more functionality out of Motion sense, some will need root access though.
There are more stuff though most of them requiere you to have root access and for me that's actually imposible as the bootloader is locked by my carrier. Though I am working on a guide where I will leave every detail about how to unlock it from any carrier. Link to that thread here.
The last link is the one that let's you create custom gestures if I am right, the others are for allowing to use motion sense on any region, use the motion sense api when creating an app and finally some of them bring more functionality to motion sense without root(I use this ones as my bootloader is currently locked by the carrier.
Hope you find this useful!
