Markdown was never meant to be previewed plain text
showmd is a native macOS Quick Look extension designed to elevate the Markdown viewing experience. Unlike traditional previewers that display Markdown in plain text, showmd renders it beautifully, providing a visually appealing and easy-to-read layout. It uniquely parses YAML frontmatter into a collapsible metadata table, making it simple to access document metadata without cluttering the main view. Additionally, showmd enhances the visualization of Agentic AI XML tags and similar elements by rendering them as labeled, bordered blocks rather than raw angle brackets, offering a clearer and more structured presentation. This tool is ideal for developers, writers, and technical professionals who frequently work with Markdown files, GitHub documentation, and skill files, especially those seeking a more polished and functional preview experience on macOS.
