Better Tabs per Tomas

Features:
- Group by Domain — Organize open tabs into groups by website
- Ungroup All — Remove all tab groups with one click
- Sort Alphabetically — Sort tabs by URL
- Close Duplicates — Find and close duplicate tabs
- Session Keepalive — Periodically ping your chosen sites to keep sessions alive, even during long AFK periods
Session Keepalive is fully opt-in: you choose which sites to protect and how often they get pinged. You can also limit pings to only sites with an open tab.
Lightweight, no external services, no data collection. Just better tabs.
