Req for Altitude Information on Flight Map of MP

Received a USB SDR receiver for picking up ADSB signals from aircraft overhead. I was successful in importing data into Mission Planner and seeing aircraft on flight map. However I was not able to see aircraft data other than ICAO callsign.

Request at a minimum, that aircraft altitude be displayed along with aircraft icon on map. If one wants additional information a mouse-over function should provide a pop-up window showing all relative data for aircraft.

In my humble opinion, we should always be aware of aircraft in our flight area and know whether they are low flyers or airway flights at high altitudes.

The issue concerns aircraft information shown on Mission Planner's flight map, but it names no files, tests, or entry points. Begin by locating the map rendering and ADS-B aircraft data handling, then determine how altitude and other aircraft fields are exposed. Done means aircraft altitude is visible with the icon and the requested additional data is available on mouse-over.
