TabArk saves your open tabs into groups you can reopen any time — like OneTab, but with a real safety net. Every change is automatically saved as a timestamped backup, so you can restore tabs after a crash or misclick. Features: - Save tabs into groups with one click - Automatic backup history (last 10 versions) - Restore any earlier version by time and tab count - Export to JSON - 100% local, no account, no tracking
