Steve,
That is a pretty neat idea. I will add it to the todo list. Hopefully the Google Earth API makes this simple.
I will also add an item to sync up multiple Global Mapper views. Right now an enterprising user could do this using the External Control API which is described on the Developers page at
GIS Mapping Software - GPS Mapping Software - Satellite Maps - Aerial Photos [Global Mapper]. It provides external control of the Global Mapper application in some ways, like setting the view, so that external application could in theory control multiple instances of Global Mapper.
Thanks,
Mike
