Feature Request: Editable mindmap, so the markdown is editable either in Text Editor or Mindmap Editor mode,

A mindmap is a great way to organize and refine a document. It's also a great way to breaking down a complex document to read and synthesize one part at a time.

The Markdown hierarchical header structure works well with the mindmap structure. Right now, I import markdown documents in XMind, where each heading becomes a node, and drag and reorder the headings as a mindmap before exporting it in Markdown.

I'm envisioning an Markdown editor that can toggle between Markdown and mindmap editing modes.

[Transno](https://transno.com/) does something similar. It renders OPML as an outline or as a mindmap, and the document structure is editable in both modes. Imagine that UI, but with parsing Markdown. It'll be tremendously helpful for visual thinkers in organizing writing and documentation, but also have use of taking pasted in long text and converting it into bitesize mindmap nodes.
