Please note that the author of the extension (me) is not the author of draw.io, I just used their embed API ;) I think you can support draw.io by spreading it or blogging about how to use their embed mode. You can also implement custom plugins. If you want to support the development of this extension, feel free to ping me on github or twitter!
