Would love to see some usecases!

Is is weird reviewing my own project? Maybe. Do I care? Don't think so.

Gameplay

This is another modpack creator mod. Imagine it as a much more powerful chisel GUI - instead of changing a block 1:1 you can craft items on the fly using resources in your inventory, offhand etc. Each crafting window can be opened by either an item or by a block in a world - turn any block into a crafting table. Each recipe category can have multiple trigger items and blocks, each with their own recipe modifiers, crafting time, consumption chance, you name it.

Performance

Has practically no impact on the game at all, especially without any recipes configured. Only reason to not give 5/5 is the lack of caching, which would slightly improve performance, while having a Crafting GUI open - still don't know if this would even be noticeable.

Aesthetics

Designs are up to the modpack author, but I provide multiple options for backgroud, borders, corners while also supporting custom textures. Furthermore I provide hooks to play sounds and spawn particles. So feel free to make your recipes visual appealing.

Note on playtime: The overall time is influenced by developing, play testing and experimenting with CraftTweaker and Groovyscript support.
