[Feature Request] editble live preview

[sasasqt]

Is your feature request related to a problem? Please describe. I'm always frustrated when editing a markdown file

Describe the solution you'd like WYSIWYG!: makes live preview editable and sync all edits back to markdown

Describe alternatives you've considered

  onDidParseMarkdown: async function(html) {
    return (
      "<div contenteditable=true>" +
      html +
      "</div>"
    );
  },

but this can not write all changes back to markdown, and lacks of editing tools like highlight, underline etc

，It keeps getting stuck on this screen and can't be edited

I would like to see buttons at the top of the preview window like in other text editors to be able to edit the markdown file in the preview window.
