Are you playing the stable build? I don't remember if it was like this on 0.F and I haven't tried experimental yet, but on 0.G the crafting list is sorted with craftable recipes at the top in white and the ones with missing requirements at the bottom in grey.
That's assuming you're talking about the actual crafting menu (&
key). If you're instead talking about the construction menu (*
key), it doesn't sort but you can hide the unavailable options with the ;
key.
