Version 1.1.0 adds built-in automatic tab grouping. You no longer need a separate extension to create tab groups—Tabbi now groups tabs using custom URL rules, collapses inactive groups on customizable timers, and manages group positions in your tab strip.

Add custom rules to group tabs automatically by domain, subdomain, path, or wildcard (*).
Set custom names and colors for each group.
Built-in pattern tester in settings to test rules before saving.
Set evaluation priority per rule to control which rule matches first.

Set custom collapse timeouts per group (between 1 second and 1 hour).
Disable auto-collapsing entirely for specific groups to keep them permanently open.
Groups containing your active tab in the focused window always stay open while in use.

Temporarily pause auto-collapsing across all groups from the popup or with a keyboard shortcut (Alt+Shift+P on Windows/Linux, Ctrl+Shift+P on macOS).
Toolbar icon updates to show when auto-collapsing is paused.

Choose what happens to tabs that don't match any rule: leave them ungrouped or route them to a fallback group.
The fallback group appears directly in your rules list and can be reordered in the tab strip or given a custom evaluation priority.

Choose between manual (drag and drop) or alphabetical ordering for tab groups.
Newly created groups are moved to their correct position in the tab strip immediately instead of staying at the end.
If you manually move a tab into another group, Tabbi leaves it there until you navigate to a new site.

Removed all innerHTML assignments in favor of safe DOM methods to meet Chrome Web Store and Firefox Add-ons review requirements.
Settings and rules are forward-compatible and persist across extension updates without data loss.
Added a clear warning dialog before resetting settings to defaults.
Updated options page with system dark mode support and JSON export/import for backups.
Full feature parity between Chrome and Firefox (138+).
Expanded automated test suite to 146 tests covering core logic, storage migration, and browser adapters.
