UnMax is a free Chrome extension developed by Jared's Coding Shack. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory.

The main purpose of UnMax is to prevent tabs from maximizing when they are detached from a maximized window. This extension is particularly useful for users who frequently work with multiple tabs and often drag them out from a maximized window.

With UnMax, users no longer have to worry about tabs automatically maximizing when they are detached. This feature helps to maintain a clutter-free workspace and allows for a more seamless browsing experience.

Overall, UnMax is a simple yet effective tool that enhances the user experience by preventing tabs from automatically maximizing when detached. It is a valuable addition to Chrome's collection of add-ons and tools.
