A comprehensive extension helps you manage bookmarks, tabs and sessions wisely.
As we always lost ourself in massive opened tabs, organizing and switching tabs in Decker's way will definitely improve your productivity.
At a glance, all tabs are grouping by website domains. But moving into details, you will see opened websites are also indented by url directories.
For regularly visited urls, it is very easy to pin or unpin them on Decker's widget.
The Decker widget can be toggled by the round button floating on the page. You can drag this button everywhere on any website pages. If you see it annoying on some website like Google Maps, you can hide this small button, there is a setting for it on Decker extension's popup.
