After using it a little bit more. I think what was hard for me initially (and is still a little cumbersome) is that the rendered markdown windows weren't always pinned if I started exploring the code.

I don't have a ton of experience using VS code so that may be something specific to me and could probably be fixed with a short intro guide on how to use this editor before I delve into a hyperdoc for a project.

Aside from that, one thing I didn't like about the UX is that if I did click a link in the rendered markdown for a specific function, let's say create.. then I didn't have a way to browse "back" to the top level README hyperdoc without clicking the readme in the file tree.
