What I'm hoping for is self-previewing Markdown -- where you use the equivalent of syntax highlighting to approximate how the Markdown will be rendered. Lines starting with # are bigger, links are links, and so on. Bullets don't even need to be changed, except possibly in color.

The split-pane approach, with one Markdown pane and one WYSIWYG pane, is such a waste of screen space, when self-previewing Markdown is all you need if you're not trying to create a published document.

A former Show HN project, bluedocs.io, offered this by default. But now it's defunct (and my notes are lost with it).

Nice. That is exactly the approach to editing I want, especially in Source Code Mode.

Of course, it's only an editor for local documents. I wonder if this could be glued to Standard Notes as a backend somehow.

If you're on Mac you can have a look at the excellent MacDown (http://macdown.uranusjr.com/) - which is also open source.
