Better list suport

Could prosemirror-flat-list be integrated into the editor, possibly as a plugin?

Milkdown’s built-in lists are not very user-friendly, while prosemirror-flat-list seems to solve most of the usability issues.

I’m not familiar enough with the editor AST and possible pitfalls to implement this myself, but I’d appreciate any guidance on the scope of work. I might try to build something with LLM's -- or possibly you may implement this feature yourselves.

@Saul-Mirone any thoughts?
