This looks very interesting! Do you have a project where I can see it in action? I would also be interested to know if you have a changelog, as I can see that you probably do regular updates. Last but not least, I am interested in compatibility and data. Are all libraries included, or do you download them externally?
I will release another update within the next weeks as I plan to include also a library for polylines/splines.
Meanwhile you can check my private homepage, where the plugin is already running.
Changelog and documentation (german only), also how to extend the plugin with additional data sources, are also available at
Regarding your question about compatibility and libraries. All libraries are included but can also be disabled individually to prevent possible double includes caused in combination with other plugins.
