Add option for collapsable fields for faster browsing

📋 Summary

Add an option in LaunchBox to make grouped library views collapsible, allowing users to collapse and expand sections for faster browsing in large collections.

❗ Problem

Navigating large libraries can become slow and difficult, especially when arranging media by grouped fields such as:

• Developer

• Genre

• Publisher

• Region

• Release Date Year

• Source

• Title (A to Z)

With many groups expanded at once:

• Browsing takes longer

• Scrolling becomes less efficient

• Large views can feel cluttered and harder to manage

💡 Proposal

Add collapsible group headers for grouped library views:

• Allow each group to be expanded or collapsed individually

• Add Collapse All and Expand All controls

• Support keyboard shortcuts for:

  • Collapse All

  • Expand All

This would make it easier to jump through large libraries without keeping every section open.

📦 Benefits

• Makes grouped views faster and easier to browse

• Reduces clutter in large libraries

• Helps users focus only on the groups they want to view

• Could improve responsiveness by reducing how much content is expanded at once

💡 Notes

• Should be optional, with current behavior unchanged by default

• Group collapse state could potentially persist while browsing

• Keyboard shortcuts would make this especially useful for power users
