## Description

"Working" is a powerful browser tab and session manager designed to organize complex workflows using nested Subgroups, customizable group colors, active tab auto-fill, and cross-group copy & paste.

Key Features:
• Multi-Level Nested Subgroups: Create structured subgroup hierarchies inside any main group to categorize research, projects, or client tasks.
• Color-Coded Tab Groups: Assign custom colors to groups and subgroups for instant visual recognition.
• One-Click Active Tab Auto-Fill: Automatically pull and save the URL and page title of your currently active browser tab with a single click.
• Cross-Group Copy & Paste: Easily copy tabs or subgroups and paste them into any workspace without losing structure.
• One-Click Session Restore: Restore saved sessions directly into native browser tab groups.
• Flexible View Modes: Access your workspaces through a quick toolbar popover, a docked browser Side Panel, or a full-page Dashboard.
• Local Privacy & Export: Export and import JSON backups or Markdown summaries anytime. All data remains 100% private and stored locally on your device.
