I am just trying to find out how AgOpenGPS works.
I could see, there is the possibility to creat fields. In the field folder is the KML File with Sections Information. So the information about the last tractor movements.
In my idea, it would be better to keep the field information like it is, and create a functionality to start jobs.
A job contains the same information like the field.kml, but it is saved in an own directory.
you can always use the same field, but start differnet jobs. And you always have the information about your jobs in the history.
When this idea would be helpfull to other peoble, I would start to develop it.
