What I would really like to see, and what I think could really help this system out, is a way to track recipes you intend to craft. Especially if there are dozens and dozens of recipes, it can be a real chore to find a dropped crafting item, sort through a million recipes because you can't remember if you needed 4 or 5 mithril nails (or something like that), and then checking your inventory to verify how many you have.
If there was a way to mark a specific recipe as "tracked" (or whatever term), and then it appears on a tab or something in one of the main menus that at a glance showed you that you have 4/5 mithril nails, 1/1 wooden boards, and 1/2 rubies would be a really handy way to keep track of the items I want to craft right now as opposed to the ones I craft at a heart/blacksmith/lab because I realize I have the materials anyway.
