I would look into it! I guess one way would be to add support for mermaid.js in hedgedoc. What I have done is build a custom parser which enables me to embed a tldraw whiteboard component on <draw/> syntax. This way your note preview document now actually consists of the original markdown text + the svg generated from tldraw, both stored as a separate file
