Download FastWorkbench v.6.0.1 [1.18.1]

This mod optimizes crafting related features. It fixes a bug introduced in Minecraft 1.12 where shift-clicking while creating a stack of items could cause instant freezes. However, it does little more than fix this issue. FastWorkbench allows you to cache the last used recipe. On top of that, it reduces the number of hits to that cached recipe by detecting changes only when the stored item in the crafting grid actually changes (vanilla retry every time something changes, like stack size). This reduces the number of matching operations from 600 to one.
