This mod, based on YaLTeR's Mouse Tweaks, introduces a couple changes to the functionality of the mouse in the inventory and in containers. The logic was ported from newer fabric versions to support legacy fabric for Minecraft 1.8.9.

Mouse Tweaks is purely client-side. There is no server-side component.
