## Version 1.0

Initial release.

Markdown opens as a rendered page in a preview tab, with Mermaid diagrams drawn
inline.

- **Preview Markdown** — renders the frontmost `.md` file and opens the result,
  ready to switch to Preview. `.mmd` and `.mermaid` files are previewed as a
  single diagram.
- **Mermaid** — every ```` ```mermaid ```` block is drawn where it sits. A
  diagram that fails to parse shows its error and its source in place, rather
  than taking the rest of the document down with it.
- **Cleans up after itself** — closing the preview tab, or the Markdown file,
  deletes the generated page; the last one out takes the shared assets and the
  directory with it.
- **Follows your edits** — on save by default, or as you type; the preview tab
  reloads itself.
- **Themes** — light, dark, or automatic, matching the system appearance the way
  Nova's own Markdown preview does. Diagrams are themed to match.
- **Also rendered** — tables, task lists, front matter (hidden), heading anchors,
  and images and links relative to the Markdown file.
