Format

### What I made
I built **Format**, a Chrome extension that upgrades how you manage tabs. It gives you a fast, OS-style tab switcher inside the browser (press `Ctrl+Shift+Space` to cycle active tabs) and integrates Google's Gemini API to automatically group open tabs into clean, colored categories.

### What was challenging
Injecting the tab switcher overlay dynamically into arbitrary web pages without breaking their original layouts or CSS styling. Getting the background worker to reliably track the tab history (Most Recently Used order) and sync it to the UI in real-time was also a fun state-management puzzle.

### What I'm proud of
The UI/UX feels incredibly fluid and premium. It follows Material 3 design principles with dynamic accent themes that automatically adjust to light/dark modes, and the AI grouping works surprisingly fast and accurately.

### How to test it
1. Load the extension folder in Chrome Developer Mode (`chrome://extensions/`).
2. Open the extension popup, go to settings, and enter your Gemini API key.
3. Click **Organize with AI** to see your tabs grouped automatically, or use `Ctrl+Shift+Space` to instantly toggle and cycle through your tabs!
