Community Inventory Overhaul: Backpacks, Tabs & Terraria Ideas

Hello Mojang, I propose an inventory & QoL ecosystem that balances progression with utility without breaking Shulker Boxes.

1. BACKPACK SYSTEM (Dedicated Back Slot)
* Dedicated Slot: A new "Back" slot that doesn't compete with Elytras.
* Crafting Tiers: Tier 1 (Leather) adds 9 slots. Tiers 2 & 3 (Iron/Gold Blocks) expand space. Tier 4 (Diamond/Netherite Blocks) unlocks max 36 slots.
* Shulker Combo: High-tier backpacks accept Shulker Boxes inside, working as a player data extension to prevent server lag.
* Visuals: Leather can be dyed. Metal tiers support Armor Trims. Banners can be attached for clan crests.

2. UI BUTTONS & TABS (Cross-Play)
* Auto-Sort: A small UI button next to the character model. It sorts inventory by "Block/Item Type" (Tools first, then Blocks, Redstone, Drops).
* Hotbar Lock: Sorting ignores the hotbar so quick-access items stay put.
* Navigation: PC (Java/Bedrock), Mobile, and Consoles navigate via visual tabs inside the inventory screen.

3. FAVORITING SYSTEM (Terraria-Inspired)
* Item Locking: Use Alt+Click (PC) or Trigger+Select (Console) to "Favorite" an item.
* Safety: Favorited items get a glowing border, ignore auto-sort, and cannot be accidentally dropped (blocks 'Q' key) into lava.

4. PARTNERSHIPS
* Collaboration: Reach out to Redigit (Terraria) for the locking and the auto sort mechanic and the "Sophisticated Backpacks" creator to balance vanilla progression.

This reduces inventory fatigue while boosting survival gameplay!
