Better MDN is a free Chrome add-on developed by cut_hand. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This handy tool aims to enhance the user experience when browsing the Mozilla Developer Network (MDN) documentation.

With Better MDN, users can enjoy the convenience of a floating MDN directory. This means that the MDN directory will always be easily accessible, allowing users to quickly navigate through different sections and find the information they need without having to constantly switch tabs.

One of the standout features of Better MDN is its ability to synchronize the directory across multiple tabs. This means that if you have multiple tabs open with MDN documentation, the directory will remain consistent no matter which tab you are on. This synchronization feature greatly improves productivity and eliminates the hassle of manually navigating through the directory each time you switch tabs.

Additionally, Better MDN provides a clickable icon that allows users to toggle the directory's visibility. This feature enables users to easily show or hide the directory based on their preference or screen space availability.

Overall, Better MDN is a useful Chrome add-on for developers who frequently refer to the MDN documentation. Its floating directory, synchronization capability, and customizable visibility make it a convenient tool for accessing and navigating the extensive resources provided by MDN.
