Tig 作者: Daniel Li

How to Use: Click the extension icon and select a color (currently only green, yellow, and red), and every time you come back to this page, the extension icon will show the color you selected. Click "Clear All Data" to remove all colors from all pages.

Why Use Tig: Ever read through a large documentation or revision site but keep forgetting if you've read that page or not? Especially if there's a lot of repetition? Well, now you can tag the page so that if it's green, you know you've consumed the page and there's no need to re-read it.
