Hi @mlclmj @tonglil,
First, thanks for your work! It is really helpful for our project.
Using your package, we encounter some API features that are not implemented and we'd like to contribute.
We posted a small PR 28 days ago fixing one of our need and wanted to add more features from the Grafana API, but the time to apply the PRs seems to be long.
We really want to use this package instead of create our own implementation of your SDK. How can we help each other to make that time shorter?
