Sorry, my English is not good. I mean that some machine recipes will also be displayed in the list, for example, recipes that need liquid. I don't know if I say so, can you understand
They (xwy694466780) probably mean: when picking a new recipe to be shown in the crafting UI, hide recipes which can not be crafted by hand.
I agree with the suggestion, it wouldn't make sense.. For example, "lubricant" or "steel plate" shouldn't be shown: https://gcdnb.pbrd.co/images/4JRcgeumXKIX.png Ores are another example.
But it's up to you to either make a setting for it or just make it default functionality.
