I use the zoom extents feature often, usually because after switching to a different terrain node, the terrain is outside the current camera view. When this happens, it is usually because the terrain is above the camera position, and so zoom extents will fill the viewport with the underside of the current terrain, and then I have to rotate the camera to a new position to see the top side of the terrain. It would be very convenient to automatically reset the camera above the terrain when using the zoom extents feature.
