It would be very nice to see our character location in the EFB map when we are in walkaround mode. This would allow to us to see where we are in relation to trails and various other geographical features near where we land the plane. It would also help us wayfind back to the airplane we left parked.
There could be additional features with this - showing the view direction and/or rotating the map with the view, leaving breadcrumbs or other personal markers, and more. Maybe some stats - distance walked, distance from plane, elevation.
But even a simple location and heading pointer would be a fantastic addition.
