I don’t understand these apps. Zed and VSCode can both render markdown. What am I missing?

They are not note-taking apps. They can't link notes to each other. They are heavy. I personally do not know anyone using VS Code for note-taking.

Can’t you just link markdown files together with regular hyperlinks?

Claude Code is my “note taking app” these days and it does a great job organizing and linking my markdown notes together, and I just open the folder in Zed and render the markdown if I need it.
