Enhancing Aloha Browsers Group Tab Feature

First, thank you for the fantastic and useful tab group feature! Here are my suggestions to improve it:

1. More Color Options: Expand color choices for tab groups to enhance visual distinction and organization.

2. Sub-Groups: Allow creating sub-groups within tab groups for better task management and hierarchy.

3. Lock/Pin Feature: Add an option to lock or pin tabs and groups to prevent accidental deletion.

4. Multiple Tab Selection: Enable selecting multiple tabs at once to add to groups, instead of adding them individually.
