a final problem is that dwarves don't choose jobs, jobs choose dwarves. Worse, when a dwarf is chosen he picks up the nearest item to WHERE HE WAS not the workshop/stockpile. Thus, you can't simply put the stockpile adjacent to the millstone, but you have to set it up to only take from links. You also have to set up a bag stockpile link to the same millstone and have both of these stockpiles properly linked to source ones. About my first point... the dwarf sees an empty spot in the source stockpile so picks something up and moves it there since its closest to him, and ignores the actual buffer stockpile that is left empty.
The point is all this hassle is a mess that we shouldn't have to deal with. We should be able to disable milling of everything but rock nuts and save our hemp for textiles from the same kitchen stock screen. In fact, it should probably be renamed "organics" or "Food-stuffs/Plants" so that we can easily control textile-plants from the same menus (as some plant fibers can be either brewed or milled instead) While we are at it, seeds (and olives) should have the "press" toggle by them as well. We can already do this type of functionality with cooking and brewing- so we can turn off brewing for everything but 1 type of plant (say to quickly gain seeds to start farming) or disable certain foods for cooking to force higher value prepared meals (Dragon roast made with quarry leaves and dwarven syrup, anyone?) In general, the inability to select what you make out of what materials is a general annoyance. We can choose what gems to cut and use in encrusting, but we can't choose WHAT to encrust. We can tell a mason to build 5 stone doors, but not out of what material. We can ask our bone carver to make ram horn crafts, but we can't ask him to make figurines specifically out of them. The same as how we can't just tell the miller to only mill 10 rock nuts and leave the dimple cups alone for now, we don't have the textiles/dwarf power to fool with them now but the farmer needed a little extra experience and we couldn't plant any more plump helmets. Don't judge me.
