Changelog

Version: 0.2.8
Date: 2026-09-28
  Changes:
    - Each lane owns 24 of the 48 slots: a blocked output lane no longer stops the other lane.
    - Each lane holds at most one full item stack of each item and quality (modded stack sizes included); more waits on the belt.
    - Status light turns red when one lane is full.

Version: 0.2.7
Date: 2026-09-27
  Bugfixes:
    - Box now takes items from a splitter, loader or linked belt right behind it and sends stacks into a splitter, loader or linked belt right in front of it (lane kept).

Version: 0.2.6
Date: 2026-09-27
  Bugfixes:
    - Fixed one output lane stopping for good when an overloaded belt brings stacked items: a full box now hands freed slots to both lanes in turn.
    - Belt stack size now follows belt stacking research exactly, including mods that raise it above 4.
  Changes:
    - Tooltips and tips describe stack size as set by research.

Date: 2026-09-27

  Changes:
    - New mod thumbnail.

Version: 0.2.4
Date: 2026-09-27
  Bugfixes:

  Changes:
    - Factoriopedia and tip scene show only belt, box, belt; box centered, feeding machinery off screen.

Version: 0.2.3
Date: 2026-09-27
  Changes:

Version: 0.2.2
Date: 2026-09-26
  Changes:

    - Own crafting menu row after belts, sorted by tier.
    - Settings window: aligned sections, 10-slot skip filter with splitter-style quality rule, circuit network section.
  Features:
    - Live Factoriopedia and tip scene.
    - Box marked for deconstruction stops and turns its LED off.
