This is on our roadmap, yes. We focused on node first because we thought that was missing (you can always spin up a devserver for component), but we'd like to introduce a browser cell which would allow you to add HTMl / JSX components.
Can you say a little more about the concrete use case you have? It helps us prioritize
Not OP but i am interested in the same idea to document components. An alternative to storybook.
Curious, are there features you're missing from storybook, or things you don't like about it?
Srcbook with AI can do the same job faster.
It would be nice to do little interactive examples, and React/MDX seems to be the easiest way to do this. I have have a similar thing wired up with https://grammar.lingdocs.com that allows for interactive components with MDX in a textbook format.
