seems to have an 'Instant Flight Plan button' and can generally get you sorted very quickly.
I was once caught out by that though....Coming back to LA from the desert, 100 miles vis in the desert, !!!!e in the LA basin. Called up and asked for IFR - I could almost hear the controller chuckle when he said "ookkkkkkaaaayyyy - hold on the paradise 270 radial, time now 10 expect further clearance at 47".....Umm, roger, cancel IFR.
