PreviewMarkdown
PreviewMarkdown adds rendered Markdown previews and thumbnails to Finder's Quick Look.
Choose it for reading Markdown quickly without opening an editor.
Preview fonts, code highlighting and optional YAML front matter make technical files easier to inspect in Finder.
Keep in mind: Launch the host app once to register extensions. The official page says image links show placeholders, and conflicting file-type ownership can prevent previews.
