Awesome App

Great to have it working again.
I like the accuracy of the position and detail of the satellite maps. This gets used all the time at work.

Enhancement requests

Sean, please have this app use Google Maps; it's simply much better. Also, after the user inputs coordinates, let the user then press the Map button and have Google Maps (or whatever map app) open with it already zoomed in and with a pin showing the location of the entered coordinates. I really need this!
