It would be nice to have at least runway layouts (if not the entire airport layout) appear once a certain zoom level is chosen, so that you could watch what runway an aircraft is approaching.
This site - www4.passur.com/jfk.html was referred to in a different post. It gives a good different point of view. However I will have to say that I was very exicited to find FlightAware and all of its options.
Maybe even if the far future displaying navaids could be a clickable option.
