Why don't some Orbx airports don't show up on the MSFS world map with the usual "black star or yellow ground"? That would be so useful for fast recognition of an advanced airport on the map. Nearly all freeware add-on airports I have, show this feature, so it can't be difficult for Orbx to add this feature to every airport.
Some examples missing the star feature: KORS, 1S2, 3W5, EGNM, EGNT, EGPB, LSZS, YMEN. There might be more.
