Tabs Outliner

About Tabs Outliner

Tabs Outliner presents all your browser tabs and windows in a tree-style hierarchical view, similar to a file explorer. You can nest tabs under parent nodes, add text annotations and notes directly in the tree, and save entire branches for later. It's built for power users who keep hundreds of tabs open and need fine-grained organizational control that flat lists can't provide. The tree structure makes it easy to see relationships between tabs and collapse branches you're not actively using.
