Decrease the size of navigation bar on Nexus

I feel that the default size of navigation bar is too huge and it occupies a lot of space on the screen. There is a simple way in which you can change the size of it if your phone is rooted.

Step1

Install Xposed Installer. Go to Framework and install neXus navbarz. Then select it and restart the device.

Step2

Open neXus navbarz. Go to navbar options and set navbar height! Restart the phone to see the change!
