The Negative Heading plugin turns lines that start with -# into compact muted headings, giving notes a lighter way to separate sections without using standard heading levels. It works across Reading View, Live Preview and Source Mode and keeps normal Markdown content such as bold text, italics and links inside the rendered line. A smart toggle command can add or remove the token on one line or across a selection, using majority based detection and preserving list markers when the syntax appears inside list items. The plugin also supports escape characters, ignores code and math blocks and uses theme aware colors with accessible heading semantics in Reading View.
