TL;DR
A recipe combinator like the one from Crafting Combinator.What?
Distinct recipes should have their own signals. The recipe combinator should show available recipes that produce a product, ingredients required for a recipe, products produced by a recipe, and which machines can produce a certain recipe. There should also options for multiply/divide by inputs and results.Basically bring the old modded recipe combinator into the main game.
Why?
The recipe combinator provided a bunch of functionality that the new options on assembling machines does not provide.If a mod provides multiple recipes or reversible recipes, then the assembling machine just chooses one. There needs to be a way to filter out the unwanted recipes. the "multiply/divide" functionality from the mod was useful for determining x number of crafting cycles needed to produce y number of products for recipes that produced more than one of the product per cycle.
