MoreGroups - subgroup your tabs

Tab Subgroups Extension Organize your browser by nesting tab groups inside each other. Create powerful hierarchies to keep your workspace clean and navigable. Features - Nested Grouping: Create subgroups by moving tabs from one group into another. - Recursive Collapse: When you collapse a parent group, all its child subgroups are automatically saved and removed from the browser to save space. - Recursive Expand: When you un-collapse a parent, its direct children are restored in a neat, collapsed state. - Color Inheritance: Subgroups automatically match the color of their highest-level ancestor ("root parent"). - Smart Priority: When creating a group from multiple tabs, the leftmost tab that already belongs to a group determines the parent. - Naming Control: - Subgroups are automatically named Parent-N. - Rename a subgroup normally, and the extension will remember it. - Type $b as a title to revert the name back to the automatic Parent-N format. How to Use 1. Create a Parent Group: Right-click a tab and select "Add tab to new group". Give it a name (e.g., "Work"). 2. Create a Subgroup: Drag a tab that is already in "Work" and create a new group with it. The new group will automatically be named "Work-1" and become a child of "Work". Manage Hierarchies: 3. Click the "Work" group header to collapse it. All "Work-1", "Work-2", etc., tabs will disappear. 4. Click again to expand. The subgroups will reappear as small, collapsed headers. 5. Deep Nesting: You can repeat this process (e.g., creating a subgroup from "Work-1") to create N-levels of organization. Technical Details Privacy: All tab data (URLs and titles) is stored locally on your machine using chrome.storage.local. No data ever leaves your browser. Efficiency: The extension uses persistent ID mapping rather than title parsing, ensuring it never loses track of your groups even if you rename them.
