Looks really nice. As someone who just found out about Milkdown and Prosemirror through this post could you clarify what this adds over prosemirror-markdown? Would it be hard to be able to do the "switch to markdown" thing they do in this example? https://prosemirror.net/examples/markdown/

I'm thinking about using something like this but would require a custom markdown extension. Would that be easier with Milkdown because it uses markdown-it?
