Ability to Quickly Navigate Playlists Alphabetically in All Big Box Views

📋 Summary

Extend the existing alphabetical navigation feature (currently available in the Text List with Details view) to all Big Box playlist views, allowing users to quickly jump through large playlist collections using left/right inputs.

❗ Problem

When browsing large numbers of playlists in Big Box, navigation can be slow and cumbersome. While games already support fast alphabetical navigation (pressing left or right to jump ahead by letter), playlists only support this behavior in a single specific view.

In all other playlist views, users must scroll sequentially through the entire list, which becomes inefficient as collections grow.

💡 Proposal

Enable alphabetical navigation for playlists across all Big Box views, matching the behavior already available for game lists:

• Press left or right to jump forward or backward by alphabet letter.

• Apply this consistently regardless of the selected playlist view type.

• Reuse the same input logic already implemented for game list navigation.

🧩 Use Cases

• Users with many auto-generated playlists (Genres, Regions, Series, etc.) want to quickly jump to a specific playlist.

• Couch or arcade-style setups where controller-only navigation is preferred.

• Users who frequently browse curated or thematic playlist collections.

📦 Benefits

• Faster and more efficient navigation in Big Box.

• Consistent behavior between game lists and playlist lists.

• Improved usability for large collections and controller-based setups.

• Small change with high quality-of-life impact.
