## Description

**Tree Style Tab in Separate Window** is a Chrome extension designed to enhance your tab management experience by allowing you to open the Tree Style Tab sidebar in a separate window. This means you can keep your main browser sidebar free to manage bookmarks or other functions, while maintaining an organized tab structure in its own dedicated window.

This extension adds a convenient toolbar button. Clicking it opens the Tree Style Tab sidebar page in a new window, and right-clicking offers the option to open the sidebar page in a tab within the current window. Please note, this addon requires the original Tree Style Tab extension to function properly. Ideal for users seeking improved navigation and multitasking capabilities within their browser.
