App: Change navigation map orientation when auto zoom

Perfect would be a switch from 3D to 2D-north. Then it is possible to get a very fast overview about the route around me and after driving a few meters it goes automaticaly back to the navigation (3d) zoom level.

We discussed similar ideas here: App: Show route overview in navigation.

I still think that after the route overview in North-Up-2D mode, it would be useful to go back to the previously defined zoom/2D-or-3D automatically, according to the preferences for regularly navigation.
