Default [Q] Navbar customisation on stock KK

I've recently gone back to stock after flashing the latest factory 4.4.3 image. I have xposed and gravity installed, however I miss the option to assign different icons to the navbar buttons.

I like to have a permanent menu button in place of the recent apps button, but with gravitybox installed I can only make the recent apps button become a menu button, however the icon remains as a recent apps icon if that makes sense.

Is there a mod available that allows a much wider ranging option for editing the navbar?

Thanks.
Bob
