for flying over mountains (especially in a microlight) the "Terrain" display is of great help, but it needs to be switched on/off to avoid confusion on regular airports. I would appreciate, if a "Terrain" button would make this easier switchable during flight, rather than the 5 touches to (de-)activate it via the layer button. Even in highly sophisticated airplanes like the Airbus, usually flying at FL 240++, it is a button right next to the NAV display.
