I'm testing it and seems to be very broken, typing things around and things jumps everywhere.
I was trying to create something like this too, because I need something that also work for mathematical writing. Let me push a version on github and update, it fixes a lot of issues.
Unfortunately it works on my own version of markdown, which is a subset of pandoc markdown, but I think one can get claude to update the parser to work for other things.
Thanks for the heads up - I pushed up a fix to the hightlighting issue.
I originally went with Milkdown (Prosemirror-based) for Atomic, the knowledge base project that I built Atomic Editor for. ProseMirror doesn't provide virtualization out of the box. For shorter notes and even moderately long content it's fine - but atomic supports syncing content from a diverse set of sources and I noticed that long documents were causing delays on initial page load and some lag during edits. I didn't find anything like it with native virtualization that felt right to me so I built Atomic Editor.
That looks pretty good, but it isn't quite there yet, for me. If you try to delete the opening fence, the closing fence turns into a closing fence, and the abstraction leaks in tables.

I'm curious when I see things more geared toward prose using CodeMirror instead of ProseMirror. Any comment on that decision?
