📋 Summary

Add middle-click auto-scroll support to the main game view in LaunchBox.

❗ Problem

LaunchBox already supports normal mouse wheel scrolling, but users with large libraries may want a faster, more comfortable way to move through long game lists or grid views.

Many desktop applications and web browsers support middle-click auto-scroll, where clicking the mouse wheel enables continuous scrolling based on mouse movement.

💡 Proposal

Add middle-click auto-scroll support to the main center game view in LaunchBox.

When the user clicks the mouse wheel in the main view, LaunchBox should enter an auto-scroll mode. Moving the mouse up or down would scroll the library continuously until the user clicks again, presses Escape, or uses another cancel action.

This could optionally be supported in the left filter/sidebar panel as well, though the main game view is the most important area.

🧩 Use Cases

• Quickly browse large game libraries

• Scroll through box/grid views without repeatedly spinning the mouse wheel

• Navigate long lists more comfortably with a mouse

• Take better advantage of fast library scrolling performance

📦 Benefits

• Improves mouse navigation

• Makes large libraries easier to browse

• Adds familiar desktop-style scrolling behavior

• Helps showcase smooth scrolling performance in LaunchBox

⚠️ Considerations

Auto-scroll should be easy to cancel and should not interfere with normal middle-click behavior if that is used elsewhere. The Game Details panel likely does not need this behavior.
