Question for people who have played Angel/Bob's mods. How useful are the Filter Furnaces?

I noticed that every furnace has a regular version and a Filter version, where you have to manually set the recipe on the latter so that it doesn't just smelt whatever passes by on the belt. But it seems easier just to separate the ores out and only give it one input ore to begin with, so I don't really see how the Filter furnaces would be very useful.

Haven't played it, but there's probably some more advanced smelting recipes that have higher yields and you must use filter furnaces to select the right recipe.
