This tool offers additional commands that streamline tab management, making it easier to organize and navigate through multiple tabs. Key features include the ability to create new groups from selected tabs, ungroup tabs, flatten the tree structure, and adjust the indentation of tabs for better visual hierarchy. These functionalities are accessible via context menus and keyboard shortcuts, providing users with a more efficient workflow.

The add-on is subscription-based, reflecting its utility for users who heavily rely on tab organization.
