great site - could it be updated to take the GPS co-ords from flight star (HDDMMMHDDDMMM e.g. N51422E01120)
It could, I suppose, but I wouldn't hold your breath to be honest! It has quite a few users now and nobody else has asked for it.
If you really want to you could add a custom waypoint and then use that. Otherwise if you know any place in the vicinity just use the place name.
