Thanks! Actually, we initially started this project with a GPX data visualization app in mind. Open Street Map achieves this well in 2D maps, and we are very interested in a 3D version. As you can try in the example/geo-viewer, manual 3D line marking is already supported. Soon, we definitely want to add the GPX data loading/displaying feature useful to hikers, mountaineers, drone users, etc.
