Hi, I know that this is a very hard request, but should be wonderful to have an instrument that permit to measure radials and distances (like a real radar). That should be useful to measure separation between aircraft, distance aircraft-points, etc...
EDIT:
Another request, possibility to activate navaids and fixes only where are necessary, because loading it the performance fall down drastically. At the moment I've done this, defining my Fixes, VORs, NDBs using the Custom Legend List, and obtaining very good performance zooming and scrolling the map.
