I’m actually really surprised that more people aren’t using this. Its a fantastic idea: An extension that lets you save groups of tabs for quick load and access at a later date. Plus you can upload and share your wads all through the extension.

• organize your bookmarks into wads
• access your wads from anywhere with just a few keystrokes
• search wads created by other users and save those that you find useful or interesting
• gain new insight into your bookmarks as other users contribute to the process of organizing and discovering web content
• open Google or Yahoo search results in tabs with a single keystroke
