Hey Product Hunt,
Over the years I've received a lo of requests for a Quick Look plugin in Marked. I've published Marked QL as a separate product. Works great with Marked 3, but doesn't require it at all. Just a solid Quick Look preview for Markdown files, complete with syntax highlighting, Mermaid, MathJax, and more. Compatible with CommonMark, GFM, Multimarkdown, Kramdown, and all your favorite Markdown flavors (powered by Apex).
