And no, converting a `#` into a H1 is not "markdown support". I want a non-WYSIWYG mode that can let me work on plain text and export it without changing a single comma or tab, optionally with a WYSIWYG presentation layer on top of that like Dropbox Paper does, but one that does not let me add non-markdown features (which would inevitably get lost when exporting and re-importing the same file, or parts of it via copy and paste).
Update: You made me look: Sadly still no Markdown support. I would have been very happy to be wrong here.
