About this extension
GitHub Flex enhances GitHub's interface with powerful productivity features that make your daily workflow smoother and more efficient.

Features:

• Wide Layout: Expands GitHub pages to use the full width of your browser. No more wasted screen space - see more code, diffs, and content at a glance.

• Table Expand: Click to expand large tables directly on the page. Table state is remembered, so collapsed/expanded preferences persist across page loads.

• Image Lightbox: Click any image on GitHub to view it in a fullscreen overlay. Easily inspect screenshots, diagrams, and visual content without opening a new tab.

• GIF Picker: Insert GIFs directly into comments, issues, and pull requests. Search from a huge library powered by Giphy - add reactions and fun to your conversations.

• Sidebar Toggle: Hide or show the GitHub sidebar with a single click or the Alt+M keyboard shortcut. Reclaim horizontal space when you need to focus on content.

All features can be individually enabled or disabled from the popup settings. Your preferences sync across devices via browser sync.

Lightweight, open-source, and built with Manifest V3. No data collection, no tracking - just a better GitHub experience.
