Legacy Mouse Tweaks
by infloat
Legacy Mouse Tweaks changes how mouse clicks and the scroll wheel move items inside inventory and container screens on Minecraft 1.8.9.
What it does
The mod is a Legacy Fabric port of YaLTeR's Mouse Tweaks, adapted for Minecraft 1.8.9. It keeps the original inventory behavior and adds a few changes to how the mouse works in container screens. Players who rely on quick item transfers during inventory management can use it without leaving the 1.8.9 version.
The mod needs Legacy Fabric API to run. Its logic was carried over from newer Fabric versions so it could work on the legacy loader. It runs purely on the client, so only the player's installation needs it and servers do not have to install anything. It is open source under the MIT License, and its source code and issue tracker are publicly available. Files were first published on 2026-02-17 and the latest 1.1.0 file for 1.8.9 followed on 2026-03-23.
Key features
RMB Tweak
Right-clicking an item stack in a container screen moves items in a way the original Mouse Tweaks mod supports for 1.8.9.
LMB Tweak with item
Left-clicking while holding an item distributes it across the slots that the drag crosses.
LMB Tweak without item
Left-clicking an empty cursor on a filled stack picks up matching items from the rest of the container.
Wheel Tweak
The scroll wheel moves items between the player inventory and open containers, one stack at a time.
