v1.2 Rendering Polish & Features

What's New in v1.2

• YAML Front Matter — Metadata between --- delimiters is extracted and displayed as a clean, styled two-column section above the document body
• Width-Adaptive Layout — Rendering automatically adapts to available width with scaled fonts, spacing, and a 640pt max content width for comfortable fullscreen reading
• Responsive Tables — Content-proportional column sizing with compact mode for narrow contexts and smart wrap/truncate hybrid for long content
• Task List Checkboxes — GFM - [ ] and - [x] render as SF Symbol circle icons with system accent blue coloring
• Cross-Context Snapshot Testing — 6 regression baselines (3 widths × 2 appearances) ensure all features work together across spacebar popup, Finder preview pane, and fullscreen Quick Look

Important: First Launch Setup

This is an unsigned release. The app will not open normally on first launch — macOS Gatekeeper blocks unsigned apps by default. You must do one of the following before the app will run:

Option A: Right-click to Open (recommended)

1. Open Finder and navigate to Applications
2. Right-click (or Control-click) on MD Quick Look.app
3. Select Open from the context menu
4. Click Open in the confirmation dialog that appears

Option B: Remove quarantine via Terminal

xattr -dr com.apple.quarantine /Applications/MD\ Quick\ Look.app

After either step, the app will open normally from now on.

Enable the Quick Look Extension

After the app launches for the first time, you need to enable the extension:

1. Open System Settings
2. Go to Extensions → Quick Look
3. Toggle MD Quick Look to on
4. Open a new Finder window, select any .md file, and press Space

Tip: The app includes a direct link to the Extensions settings pane — click "Open System Settings" in the app window.
