Cool stuff
Gotta say tho, IndexedDB isn’t really reliable thing to use for such app.
I would suggest you create “native” app for OS.
Wrap your app in Electron or Tauri (recommended) with SQLite database for better persistence. And that way it would also be portable :)

Love this approach. Local-first + IndexedDB is underrated for note tools where privacy and speed matter.
The smart HTML → Markdown paste and command palette are small details that make daily use much smoother.
Feels built for people who actually write in Markdown, not just demo it.

I found this simply brilliant. I have a lot of difficulty remembering the specific &quot;codes&quot; of markdown, and this program provides a great solution to what I was struggling with at work.
