Tab Auto Grouper od tadayuki.dev

Tab Auto Grouper keeps a busy tab strip organized without any manual sorting.

• Group tabs into Chrome tab groups based on domain, URL, or title rules
• Automatically reuse existing groups instead of creating duplicates
• Optional catch-all group for any tab that doesn't match a rule — keep
  everything else together in an "Others" group
• Sort tab groups to the left or right of your other tabs
• Close duplicate tabs with one click
• Fully customizable rules — edit, reorder, add, or remove them from the
  options page
• Export and import your settings as JSON

Everything runs locally in your browser. Tab Auto Grouper does not collect,
transmit, or share any of your browsing data.
