Product scope

These docs describe the released Chrome extension. In this version:

• unpinned tabs are assigned to categories using domain and page-title rules;
• ordered Tab Rules and Context Profiles can refine those assignments;
• groups can optionally sync to native Chrome Tab Groups via Tab Groups Sync (BETA);
• Group Mirror Mode can instead project native groups for direct editing and selection;
• the popup is the default host; Chrome's Side Panel and a dedicated window are available as alternative hosts;
• search, statistics, duplicate review, recommendations, sessions, and multi-window tools are available from the popup;
• custom group names and colors can use Chrome Sync; and
• session exports are JSON-based .tabsession files under your control.

The behavior described here does not cover unreleased builds or other browsers.

Safety conventions

Actions that close tabs, replace the current session, merge windows, or import a session file are marked with a warning before the affected steps. Pause at those warnings and review the scope shown by the extension.

Labels in bold match the English interface. Keyboard shortcuts appear in code formatting. If the interface differs materially, verify the installed version before continuing.
