AI Summary: The task involves improving the osu!mania gameplay experience on desktop platforms, specifically addressing the lack of a customizable touch layout option. This requires modifying the existing settings to include a setting for touch layouts on desktop, potentially separating portrait and landscape modes, and possibly renaming the setting to be more inclusive of touch devices. The change should allow players to choose between a traditional layout and a touch-friendly layout with larger input zones, improving playability on devices like the Steam Deck.
