disabling of the navigation bar and use of alternative navigation-apps

many have been annoyed at the A9 fact that the navigation keys are not located next to the fingerprint reader and narrow down the screen.

I looked around and found the site http://www.androidexplained.com/how-...avigation-bar/
So I turned off the Menu bar permanently.
The question now is: what soft-menu app should I use?
I've tested:
Pie Control - very basic app
GMD Auto Hide Soft Keys - occasional crashes - configuration options low - hides the menu bar without changing qemu.hw.mainkeys
LMT Launcher 2.4 beta 4 http://forum.xda-developers.com/show...ight=no+action - very powerful and fast and fully configurable!
LMT Launcher is my preferred app, but I have not yet managed to take advantage of the current betas 2.5... - only recent apps work for me so i've installed LMT_v2.4.apk.
One more limitation of these apps: the Camera app disables LMT-menu and Pie Control - just GMT may show its menubar.
That's the reason why I activates the fingerprint scanner as a home button.

Maybe you have another solution - for example, Tasker task to temporary suppress the menu-bar ...
