Crafty checks your quest log for Workorder quests, and tries to figure out how much of them you can do from items in inventory and bank. It is smart enough to handle situations such as having some bolts of cloth (but not quite enough) and also needing some plain cloth for other things. I think.

New in 0.5: When you have all your materials, Crafty switches to showing the quest items you need to make.
New in 0.7: "crafty -s" may keep the window from re-autoshowing until you log in, rather than on zoning and such.
