MouseTweaks

A port of Mouse Tweaks by Ivan Molodetskikh (YaLTeR) to Horizon, as a native mod, with all seven of the original's options.

• RMB drag: hold the right button with a stack and drag over slots to drop one item into each.
• LMB drag: with an item on the cursor, drag to gather the same items; with Shift, quick-move every slot you pass.
• LMB drag with an empty hand + Shift: quick-move every slot you pass.
• Wheel tweak: the wheel over a slot moves items one at a time between your inventory and the container, crafting results included. Search order, scroll direction (normal, inverted, position-aware) and item scaling as in the original.
• Works on every container screen and on the player's slots in the creative inventory.
• While it is on, it replaces Horizon's built-in Extras > Mouse Tweaks.

Settings: Options > Mods > Mouse Tweaks. Every action is an ordinary slot click, so it works on servers too.

Built for Horizon Nightly 2026-11-07 (2ebf00a). Native mods are compiled into the game and are not sandboxed: build only code you trust.
