The following feature requests are currently being worked on:
Integrate active runways detection for landing and takeoff runways into the GUI for both the current airport when on ground and the destination airport.
Filter airport display by runway length
And these requests are going to take a little longer:
Ability to sync the time in PSX to the RealTraffic time.
In the USA, there are many airports. The map display can get cluttered with the airport identifiers, making it hard to read the traffic tags.
Therefore, how about a feature to exclude airports on the map with runways shorter than a certain cutoff, maybe user-specified, or fixed at something like 10,000 feet? The idea would be to keep major airports for situational awareness, while filtering out all the tiny ones that can clutter the map.
(Always displaying the departure and destination airports, regardless of runway length, of course.)
