- Live Markdown preview with fast rendering
- Optional LaTeX/Math formulas rendering (MathJax)
- Export/print to PDF and save source as Markdown
- Open existing Markdown files locally
- Distraction-free modes (editor only, preview only, or split view)

- Support for page breaks when printing/exporting
Use Cases
- Writing technical notes with Markdown and math equations
