What we really need here, of course, is a nice dialog to allow user selection of NMEA
sources, destinations, multiplexing, and sentence handling.....
But we just don't have the resources to tackle this now.
We could start the process by asking for user input.
Suggestions for functionality? Mocked up (or ripped) screenshots? Intersted users may want to start a discussion thread for this. I'm sure it will be a popular topic....
Meanwhile, I will add code that will allow RMC to be sent to A/P by manual config file editing. This will show up in the next Beta.
