Simple Todo Popup

A lightweight to-do list that lives in your browser toolbar. Click the icon, jot down tasks, check them off — no accounts, no backend, no dependencies.

Install from the Chrome Web Store →

Features

• Quick capture — add a task from the popup with a click or the Enter key
• Check off & reorder — mark tasks complete, or drag and drop to reorder
• Delete — remove tasks you no longer need
• Themes — light and dark, defaulting to your system preference with no flash of the wrong theme on open
• Adjustable text size — small, medium, or large
• Persistent — everything is saved locally via chrome.storage.local, so your list survives restarts

Tech

• Manifest V3 Chrome extension
• Vanilla JavaScript, HTML, and CSS — zero build step, zero runtime dependencies
• chrome.storage.local for persistence; the only permission requested is storage

Development

Load the extension unpacked:

1. Open chrome://extensions
2. Enable Developer mode (top right)
3. Click Load unpacked and select this project folder

Edit the files under browserAction/ and reload the extension to see changes.
