All crafting items should be accessible without having to swap items out and make room. Without having to check a separate box, accessible only in certain areas, to see if you can or can't make something. If you have the item, you can craft with it.

FFXIV out shines many a game but this is 1 feature I am surprised hasn't been finished. Considering the grand amount of items and that we can have up to 8 retainers. I'd imagine most people would really appreciate this feature for even doing their dailies.
