I support that suggestion. Would be useful to have. A "Nearest" tab on the sidebar would slide open on tapping and reveal a list of airports, VFR reporting points, NAVAIDs and maybe even geographical features (towns, landmarks, etc.) sorted by distance from current position. Choosing one from the list would highlight it on the map. Maybe a "long tap" would open a separate list giving me the option to either "Show on Map" (the default), "Track waypoint", "Insert waypoint into route" (between current position and next point on the route).
