Decker is a free Chrome extension developed by OWhale Inc. that aims to help users manage their bookmarks, tabs, and sessions in a more organized and efficient manner. With the ever-increasing number of open tabs, Decker provides a solution to the problem of getting lost in the chaos.

The extension groups all open tabs by website domains, allowing for a quick glance at the tabs currently in use. However, it goes a step further by indenting opened websites based on their URL directories, providing a more detailed view of the browsing hierarchy.

One of the standout features of Decker is its ability to easily pin or unpin regularly visited URLs on the extension's widget. This allows users to quickly access their favorite websites without the need to search through a multitude of tabs.

To make the extension even more user-friendly, Decker provides a floating round button that can be toggled on any webpage. This button can be dragged and placed anywhere on the page, giving users the freedom to customize their browsing experience. If the button becomes intrusive on certain websites, such as Google Maps, it can be hidden through the extension's popup settings.

Decker is a valuable tool for those who frequently work with multiple tabs and want to improve their productivity. With its intuitive interface and helpful features, it offers a convenient way to manage bookmarks, tabs, and sessions in Chrome.
