Greetings,
I'm not sure if this is an update to an existing feature, or if it falls into a new feature request in which case I'll add a topic through the uservoice site. Are there any plans to implement the updated immersive mode that android 4.4+ supports? It removes the nav buttons & status bar entirely until a user taps the screen, thus allowing for more screen real estate to be used. The Kindle App is one example of an app that supports this.
The following link explains in more detail:
