GRouteLoader does not list any route names in the RWGPS route list, thus you have to look up a route number prior to using the app. That's unfortunate and less then useful (IMO).

I had thought the RWGPS route list got re-ordered when you opened a route, that's not the case, so Pinning a route is likely the easiest way to keep a limited set of routes ready for download and viewable in the RWGPS iW app.
