## Description

Tree Style Tab is a powerful browser extension that organizes your tabs as hierarchical trees. New tabs opened from a current tab are automatically grouped as children, enabling clear visual branching and a tidy tab bar. Easily collapse or expand branches to manage tab clutter, and rearrange tabs via drag and drop to suit your workflow.

This extension acts like a visual browsing history and groups related topics, enhancing navigation especially during research or multi-tab browsing. Useful features include toggling the sidebar with the F1 key, bookmarking integration, session management, and APIs for extension developers. Tree Style Tab supports various helper add-ons to extend functionality, making it a versatile tool for improving productivity and browser tab management.
