1.  Add WAAS ability for the GPS.  For those of you who don't know, WAAS provides vertical guidance to a GPS approach, much like an ILS.  These approaches are becoming more and more common, as they don't require the ground equipment required for an ILS.
2.  When filing a flight plan, allow you to select a gate for the destination, much like you can for the departure.  That way you can select what gate you will be directed to on landing, instead of a random gate.
