Hello. I really love your mod, but there is one annoying problem with portable crafting. The fact is that starting with Minecraft 1.12 there was a problem with workbenches. When crafting a stack of any item via Shift-click, it is not crafted immediately, but freezes for a few seconds. The FastWorkbench mod fixes this problem, but unfortunately, this fix does not apply to the portable workbench from your mod, and therefore crafting in it is not very pleasant. I really hope you fix this, it shouldn't be too difficult. Thanks for attention.

The FastWorkbench GitHub page has instructions on how to implement its methods in your mod https://github.com/Shadows-of-Fire/FastWorkbench
