Quick Look Plugins Overview

An excellent collection of useful Quick Look plugins for developers. Each Quick Look plugin can be downloaded and installed manually or installed using Homebrew Cask. My favourites are QLColorCode which allows you to preview source code files with syntax highlighting, QLMarkdown for previewing Markdown files in their HTML form, and QuickLookJSON for previewing JSON files with pretty formatting and collapsible sections. The repository owner is also accepting pull requests so you can suggest your own plugins.
