Tab Subgroups Extension

Organize your browser by nesting tab groups inside each other. Create powerful hierarchies to keep your workspace clean and navigable. To try this extension yourself, click here

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".
3. Manage Hierarchies:
   • Click the "Work" group header to collapse it. All "Work-1", "Work-2", etc., tabs will disappear.
   • Click again to expand. The subgroups will reappear as small, collapsed headers.
4. 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.

Permissions

• tabGroups: Used to create and organize groups.
• tabs: Used to save and restore tab URLs.
• storage: Used to persist your group hierarchies across browser restarts.
