Preview pane

Optional right-side pane with details and Quick Look previews while you browse.

Live 4K Inspector & Code Preview (⌥⌘I)

The right-side Inspector / Preview Pane (⌥⌘I) lets you inspect source code, Markdown, 4K media, PDFs, and multi-item selections without opening heavy external editors.

What it shows

  • Syntax-Highlighted Code & Text Viewer (30+ Languages):
    • 1-Click Pretty JSON: formats and indents minified .json files in place.
    • Light / Dark Code Theme Toggle, Line Numbers (#), and Word Wrap toggle.
    • Inline Find in Preview Filter: filter code lines matching a substring in real time.
    • Live L · W · C Telemetry: displays exact Line, Word, and Character counts plus a 1-click Copy Code button.
  • Markdown, Media & PDF Previews:
    • Formatted Markdown preview renderer.
    • High-resolution image, video, audio, and PDF preview cards with pixel dimensions (W × H), duration, and page count badges.
  • Quick Copy Bar: 1-click buttons to copy the item’s Name, POSIX Path, or Markdown Link ([filename](file:///path)).
  • Multi-Selection Inspector Mode: when multiple items are selected, the Inspector displays their combined byte size, lets you assign 7-color macOS Finder tags in bulk, and provides 1-click Batch Rename (N), Compress to ZIP, and Add to Quick Shelf actions.

How to use it

  1. Select an item in the list/grid.
  2. Read the preview/details on the right.
  3. Press Space for full Quick Look when you need it.

You can enable/disable the preview pane in Preferences.

When it’s worth keeping on

  • You often work with images and need quick dimensions/metadata checks.
  • You browse lots of documents and want “glance first, open later”.
  • You do file triage (keep/delete) and want details without extra windows.
