About Peek-a-Repo
Peek-a-Repo lets you instantly preview GitHub files, folders, and images by hovering over them — no clicks, no page loads.
✦ FEATURES
• Code preview — hover any source file to see syntax-highlighted code in a floating popup
• Folder preview — hover a folder to see its contents as a mini file tree
• Image preview — hover image files to see them rendered inline
• "View more" — expand truncated files without leaving the page
• Smart caching — repeated hovers are instant, no extra API calls
• Smooth scrolling — momentum-based scroll inside the popup
✦ SETUP
