As nice as it is to take off the headset, remove your phone, swipe around for a new app, re-insert the phone, fix the inevitable alignment issues, and put the headset back on each time, Daydream does it best - closing a VR app simply returns you to Daydream's immersive launcher without breaking VR. This should be the norm, not an exception. In fact, Google's Android Auto app (and the numerous "Car Mode" launchers it spawned) do the same thing. Why not Cardboard? If I'm understanding OP's question right, this is the kind of in-headset thing he's looking for.
Closest I've found is VR Launcher which takes you "home" when shaking your head. Works alright, but has trouble finding all of my VR apps.
