As I create my courses in GC, I see a need for folders to group and store my various trips (for my 800 or 810) I don't want to delete older courses (cycling trips) incase I repeat some later. In my case I have close to a 100 courses (I delete many now as well), which are my "local rides", as well as trips: to New York 2013, Florida keys 2013, Boston 2013, France 2012, Italy 2012, Hungary 2014, Quebec 2014, etc. This idea of folders would allow me and others to group courses for better access control to my routes. This folder ideas would be needed in full GC and in the GC mobile app. I normally just add my current courses to my 810 so I don't see a need for it in the 810.
