Auto-Show Sidebar on Mouse Hover

📋 Summary

Add an option for the LaunchBox sidebar to automatically show when the mouse cursor hovers near the left edge of the window.

❗ Problem

Users currently need to manually show or hide the sidebar when they want access to platforms, playlists, filters, or other navigation items.

This can interrupt browsing, especially for users who prefer a cleaner main view with more space for games.

💡 Proposal

Add an optional auto-hide sidebar mode.

When enabled:

• The sidebar stays hidden during normal browsing

• Moving the mouse to the left edge of the LaunchBox window reveals the sidebar

• Moving the mouse away hides it again after a short delay

🧩 Use Cases

• Keep the game grid cleaner while still having quick sidebar access

• Quickly switch platforms or playlists without manually toggling the sidebar

• Improve usability for mouse-focused desktop setups

📦 Benefits

• Saves screen space

• Makes navigation quicker

• Reduces manual show/hide actions

• Gives users another layout customization option

⚠️ Considerations

The feature should be optional so users who prefer the current fixed sidebar behavior can keep it unchanged.
