• Appearance switching. A new View → Appearance submenu (System / Light / Dark), applied app-wide and remembered across launches. Default follows the OS; the System item is labeled with its resolved appearance (e.g. “System (Dark)”).

Fixed

• Copying no longer pastes light-grey text. Selections copied from the preview in dark mode now use standard text color when pasted into other apps, instead of the near-invisible light grey.

• Active stylesheet indicator in the document info bar. A paintbrush icon plus theme name show which CSS is currently rendering the document, including a default label for documents without a theme: key (attributing the bundled preview.css). Click the paintbrush to open the resolved CSS file; click the name to copy its full path. Unresolved theme names are tinted orange.

Changed

• Document path in the info bar now shows the filename only, with the full tilde-abbreviated path moved to a hover tooltip. The copy button next to the filename still copies the full path.

• Document-level stylesheets. Add theme: <name> to a markdown file's YAML frontmatter and a matching <name>.css is layered over the preview for on-screen rendering, Print…, and Export as PDF…. Resolution order: ~/.config/vmarkdown/stylesheets/ → ~/Library/Application Support/com.vendasta.vmarkdown/Stylesheets/ → bundled themes. The markdown source is otherwise untouched.
• Themable CSS variables on :root for headings, the horizontal rule, admonitions, and the body/mono fonts. Override only what you want; raw selectors still available for power use. Full reference in docs/stylesheets.md.
• Bundled sample themes: serif (book-style italic), compact (tight spacing for runbooks), colorful (heading hierarchy by hue).
• Stylesheets submenu in the File menu with Reveal commands for the user-config folder, Application Support folder, and bundled themes.
• Live-reload for theme stylesheets. Each open document watches its resolved CSS file via the same hybrid VNODE+FSEvents watcher that backs the markdown source — edits, atomic-rename saves, deletions, and post-deletion recreations all flow through to the preview without a markdown re-render.

• Print (⌘P) and Export as PDF… (⌘⇧E) in the File menu. Both route through WKWebView.printOperation so the rendered preview — including syntax-highlighted code, KaTeX math, Mermaid diagrams, admonitions, and YAML attributes — comes out paginated with the same fidelity as the on-screen view. Export skips the print panel and writes directly to the path picked from a Save dialog. The save dialog has an Include YAML Attributes toggle so the exported PDF can omit the frontmatter block. Print waits for any in-flight Mermaid/KaTeX async render before triggering the operation.
• @media print styling: forces a light palette regardless of system appearance, hides the scroll progress bar, comment anchors, find highlights, and external-link arrows, expands content to the full page width, and adds page-break-inside avoidance for code blocks, tables, blockquotes, admonitions, and YAML attributes.
• POSIX permissions in the document info bar. Files display their 10-character ls -la-style mode string after file size.

• About dialog drops the inline changelog. The credits area now carries a single “View Changelog” link that opens the bundled CHANGELOG.md in a regular vmarkdown preview window via a new vmarkdown://changelog URL scheme. The real preview pipeline (scroll sync, find-in-doc, mermaid, KaTeX, admonitions) now renders the changelog instead of an ad-hoc subset.

Added

• Auto-update via Sparkle 2.x. Daily background checks against this appcast, on-demand “Check for Updates…” menu item, EdDSA-verified update integrity.
