I asked on StackOverflow, but is it possible to have multiple waypoints for a route? Google Maps will optimize a route with up to 23 waypoints, but I'm not able to find if this library supports it?

It's simply a wrapper around DirectionsRenderer. Anything you can do with native google.maps.DirectionsRenderer can be done. Please figure it out yourself.
