Edible Backpacks

Open and close the backpack

• Toggle button on the inventory screen (20×18, edible-backpack glyph), plus an unbound hotkey under Options → Controls → Edible Backpacks.
• Client config (ediblebackpacks-client.toml): turn the button off entirely, or anchor it above the shield slot (default), beside the recipe-book button, or at your own x/y.
• Closing is a real lock rather than a hide — the panels refuse items on the server too, so a shift-click while closed just does what vanilla would.

Shift-click

Shift-clicking an inventory item now runs vanilla's hotbar↔inventory shuffle first and only overflows into the backpack when that has nowhere to put it.

Recipe book

The upgraded-backpack recipe unlocks in the recipe book once you have an edible backpack in your inventory (3×3, so it shows in a crafting table's book).
