Music Machine - 1.20.1 Forge Backport Release

The long-awaited backport to Forge 1.20.1 is finally here! This release brings all the core features of the 1.21.11 NeoForge version down to 1.20.1, with a handful of brand-new UI improvements to make customizing your soundtrack even easier.

✨ New Features & UI Overhaul

• Biome Sub-Categories: The massive "Overworld" track list is now beautifully organized! Songs are grouped by the specific biomes they play in (e.g., Forests & Jungles, Desert & Badlands, Deep Dark), making it much clearer where each track naturally occurs.
• Toggle All Button: A highly requested feature! Added a shiny new "Toggle All" button to the bottom of the config screen so you can instantly enable or disable every track in your current tab with a single click.
• Decluttered Tabs: To keep the category bar clean, the Swamp and Underwater tabs have been folded directly into the Overworld tab as their own sub-categories.

🐛 Bug Fixes & Under-the-Hood Improvements

• 1.20.1 Sound Mapping: Re-mapped all internal track logic to properly hook into Minecraft 1.20.1's legacy sounds.json paths, ensuring all C418 and newer tracks trigger perfectly.
• Fixed "Legacy Profile" Silence: Fixed an issue where selecting the Legacy profile would occasionally cause the game to stop playing music entirely.
• Fixed Long Pauses: Fixed an underlying engine issue that caused the game to wait an unusually long time to play the next song after changing configuration settings.
• UI Readability: Added a darkened background overlay to the config screen so text is always readable, no matter what your Title Screen panorama looks like!
• Codebase Organization: Refactored the repository structure so both the 1.21.11 and 1.20.1 versions can be maintained side-by-side.
