I don’t want Notes to become a Markdown editor. I think that would be confusing for the majority of users. What I would like is for it to understand Markdown syntax and just convert it to the right thing. If I type “# My Note”, it should convert that to note title format. If I type “## Heading” it should convert it to a heading format, and so on.

Most apps do this already, to some extent. If you start a line with a - or an *, the app will convert it to a proper indented list. Heck, even Microsoft’s apps do this. I’m just asking for it to handle a few more things.
