Description

Travelers Backpack Stack Extension

Adds a customisable stack limit to the backpack slots in Traveler's Backpack.

By default, items in the backpack can be stacked in quantities of up to 256 per slot. This value was chosen to provide a moderate increase and can be adjusted via the configuration file.
A more convenient in-game configuration using Modmenu is planned for future versions.

Why choose this mod?

  • More space: Larger stack sizes = more room in your backpack
  • Targeted: No effect on normal Minecraft stack limits outside the backpack
  • Lightweight: Simple and designed for a single, clear purpose
  • Efficient: Perfect for players who want to use their backpack more efficiently

Features

  • Increases the stack limit in backpack slots. Default: 256
  • Currently adjustable via the configuration file
  • No known incompatibilities
  • Only the backpack stack limit is changed
