Unlike other tab managers, Tree Style Tab displays your tabs in a TREE structure. Tabs are automatically organized by their parent-child relationships — any tab opened from another tab becomes its child. This gives you a clear, hierarchical view of your browsing context. With DRAG & DROP, reorganize your tab tree freely — move tabs between groups, reorder siblings, or nest as children. A live indicator shows exactly where the tab will land. 【Features】: • Tree View - Automatic parent-child tree with collapse/expand and +N badge • Tab Groups - Native browser tab groups with 9 colors, synced collapse, inline edit • Drag & Drop - Rearrange tabs anywhere in the tree, even across groups • Search - Filter tabs by title or URL instantly; bookmarks included (up to 30 results) • Web Search Fallback - No match? Press Enter to search the web directly • Workspaces - Save, preview, edit, and restore tab sessions (Side Panel) • Tab Marks - 5 mark types with colored favicon badges (Side Panel) • Dark / Light Theme - Automatically adapts to your system preference • Visual Indicators - Favicon, loading spinner, active tab highlighting • Collapsed Badge - Shows hidden children count when branches are collapsed 【NOTICE】: Tabs opened before installing this extension will appear as separate root nodes (no parent-child relationship can be detected for pre-existing tabs).
