Traveler's Backpack Stack

TBStack

  TBStack is a lightweight add-on for Traveler's Backpack that removes vanilla's 64-item ceiling inside backpack storage slots. Fill a single slot with 1024 cobblestone, carry a stack of swords, and stop juggling dozens of half-empty slots.

  Configurable stack limit — choose 128, 256, 512, or 1024 items per storage slot.

  Unstackable items stack too — tools, weapons, armor, ranged weapons, enchanted books, empty shulders, beds, potions, horse armor, milk buckets, totems of undying, and every other`maxStackSize = 1` item can stack in packs of 2, 4, 8, 16, or 32.

  Readable counts — the slot counter auto-scales so large numbers never spill outside the slot.

Important Notes

  -Only identical items merge. Two swords with the same durability will stack, but items with different enchantments or damage never mix. This is vanilla behaviour and keeps your gear safe.

  - Backpack storage slots only. Your player inventory, hotbar, and chests keep vanilla limits, so over-stacked items never leak out.

  - Usage works normally. Drinking a potion or using a tool consumes just one item from the stack.

  - Lowering the limit never destroys items. Existing oversized stacks stay intact; they simply can't grow any further.
