exists.
Research, docs, email and three half-finished shopping carts, all in one tab strip. Finding anything means squinting at favicons.
Chrome has tab groups, but setting them up by hand every morning is its own chore.
Before
- Forty favicons in one tab strip
- Setting up tab groups by hand
- Losing a research layout when you close it
With TabCluster- Tabs grouped by site in one click
- A preview before anything moves
- Workspaces saved for later
