TabNest

TabNest is a minimalistic, open-source, productivity-boosting Chrome extension designed to enhance multitasking. It allows you to save all the tabs in a window for later use. With just one click, TabNest saves all tabs and groups in the window, then closes it—reducing clutter and freeing up system resources. You can easily access and reopen the saved tabs, making the switch between projects or tasks seamless.

Features:

• Save all open tabs in the current window for later use and close the window.
• Reopen saved tabs in a new window with a single click. TabNest saves and restores the exact tab and group configurations from when they were saved, including group name, color, collapse status, and active tab.
• Update, rename, and delete saved links.
• Sync saved tabs across devices using Chrome account storage.
