Honestly all I really want is bold, italics, bulleted lists, and code blocks. If I can squeeze in quotes I'd take that too. Snort Astral Damus Probably more.

Ok, this idea might be incredibly insane and stupid but hear me out… would it be possible to invent a form of markdown that uses null/whitespace characters as delimiters, that way it would just render normally in clients that don’t support it?

I guess the point is to keep the notes human readable? what about super long URLs linking to images? those often make the text content annoying to look at... I guess "all" clients agree to render those URLs as images...

Images could render automatically, astral.ninja does it.
