Cool. I've had feedback from another guy doing fairly similar things.

The "JS function" for vector background layers is indeed on the todo list.

When I load a GPX trace in P2 it's automatically visible, using the
gpx.css style sheet. Is this not working for you, are you using an

There's already code in the gpx.css file to show waypoints along with
their text:
