Would it be possible to create an add on that could show an item compare tooltip comparing the currently equipped slot item to an item you are going to craft? Right now, you can't see what you currently have equipped when you are in the crafting window (at least that I can figure out). I don't know if the API is flexible enough to allow this or not, but I'd love to be able to see which pieces I can craft that are better than what I currently have.
