Yes, I'll wait.
And Phonegap NavigationBar (hide and auto hide navigation bar, Phonegap extension) will solve the crosswalk navigation bar problem.
I purchased the the NavigationBar plugin but it is not working as desired, perhaps because it was created before XDK 1332's immersive full-screen mode?
With auto hide on, whenever the screen is touched the navigation bar appears and then hides itself, it also changes the screen size when the navigation bar appears rather than overlaying the screen.
With auto hide off, the navigation bar appears and stays there throughout, overriding the immersive full-screen mode.
Perhaps the plugin would be more useful if it could detect when the navigation bar is visible and only hide it then.
