Blazing Tab Switcher Chrome Extension

Ultra-low-latency tab switcher triggered by the default Ctrl+P (Cmd+P on macOS) shortcut, rendered directly into the active tab.

Features

• Manifest V3 service worker with hot caches of tab metadata.
• On-demand content script injection with a minimalist overlay.
• Keyboard-centric navigation supporting Tab/Shift+Tab, arrow keys, Enter, and Escape.
• Real-time updates as tabs change, ensuring accurate titles for the MRU list.
• Lightweight vanilla JS/CSS footprint optimized for responsiveness.
• Configurable overlay appearance with horizontal layout, tab thumbnails, and adjustable text/thumbnail sizing.

Development Workflow

1. Load the extension via chrome://extensions → Load unpacked → select this directory.
2. Open the service worker via the extensions page for live console logs.
3. Trigger the command with Ctrl+P (Windows/Linux) or Cmd+P (macOS), or remap it via Chrome keyboard shortcuts.
4. Modify files in background/, content/, or docs/ as needed and reload the extension.
