Thanks for sharing the roadmap, it's very helpful!

Seems like the suggested "project modules" would solve some of my problems 🎉

Would love to see some priority on the new features? In what order are they to be implemented? As many other am I expecting Helm 3 to come very soon :)

For me, the development loop is more important than the "run skaffold in CI" part.
