I love these mods, but often it feels like I'm using every different ore for each task. For example, engine units require coal, iron, lead, copper, aluminium, wolframite, and zircon. This leads to a feeling of each ore being similar and not having the personality of being used for different things (for example, iron for buildings, copper for circuits, etc.). Could you add an option (perhaps in advanced settings) to make some recipes require fewer different things? I know this is asking a lot, will probably make my own mod that does this if you don't.
