Basically, when you to to rent an airplane to fly, you get the dialog box that lets you narrow down what you are looking for, plane type, location, etc. It would be very helpful (to me at least), to have those results also display on the world map so you can visually see the locations of the plane and location options you are interested in.
Perhaps it needs a bit of programming, but it could be I suppose like the actual layers or options in the right tab. As now there’s an option to click and view owners airports, or airports with percentage given, maybe it could be added renting spots (airports)..
