aha! covering npm packages makes sense. I briefly forgot that I hadn't publish that one on npm. I wonder if vscode extensions are published on npm... umm...
I'm glad you have all those future features planned.
As for testing, I think that badges are often times not enough. I'd like to see if tests exist at all in the first place, and the quality or helpfulness of those tests. But maybe I'm in the minority for that, so ask other users for confirmation.
:D
