Can i edit recipes?
Built-in recipes too much costs.
And removed marker plus push to build very expensive flex marker.

Use data pack.
You can add completely new recipes.

Don't ask me how to create it. There are a lot of information and example.

@Kotori316 would be nice
if you have this info in your wiki :
