S9 Navigation bar (No Root)

Dear user, I spent most of my time completing this new application. I hope this is a perfect improvement over the previous version.
In this new version, I'm still developing new features, but what's better than the previous version? I will answer that question right below:
More lightweight application
And it will support for android 4.1 (Jelly bean up). That is, users with lower versions can use it
Smoother transitions
Improved performance
The features are improved and more accurate
Provide more gestures with each button
Add more features with each gesture
Here are the gestures with a navigation button
click
press and hold (long press)
swipe up
swipe down
swipe left
swipe right
and two bonus button in the left and right side of navigation bar
I hope you will support this new version so that I can improve the application. Thank you for accompanying me all the time.
