Right now, there appears to be a severe problem with having dozens of different animal parts along with the different clothing types. It makes the stockpile screen extremely cluttered and difficult to work with. To the point of having Veok aggregate all the furs into a few types.
So I suggest there being adjustable specificity when in the stockpile screens that can lump things together more effectively. So that you have different "views" set to show the items stacked in different ways.
So there could be something like this to show all the contents in their extended glory:
Material: Specific
Item Type: Specific
Quality: Specific
Bear Leather Slipper [4]
*Bear Leather Shoe* [2]
Weasel Leather Slipper [2]
*Cow Leather Shoe* [4]
Woodchuck Bone Earring [1]
Ash Ring[17]
-Ash Ring- [3]
+Ash Ring+ [5]
Rabbit Leather Hood[1]
A mode to aggregate types:
Material: Super
Item Type: Specific
Quality: Specific
Leather Slipper [6]
*Leather Shoe* [6]
Bone Earring [1]
Wood Ring[17]
-Wood Ring- [3]
+Wood Ring+ [5]
Leather Hood[1]
A mode to condense quality:
Material: Super
Item Type: Specific
Quality: Ignore
Leather Slipper [6]
Leather Shoe [6]
Bone Earring [1]
Wood Ring[25]
Leather Hood[1]
Another mode to ultra-condense things:
Material: Any
Item Type: Super
Quality: Ignore
Clothing [13]
Craft [26]
Each material can be represented as specific (goblin bone, poplar, granite), the super-type of the material (bone, wood, worthless stone), or ignored completely. It would also be possible to create groupings of materials. For instance, you could create a category of "grey stones" or "rare bone" and use it with stockpiles so that every individual type doesn't need to be set each time.
Similarly, the quality can either be shown, ignored, or split, putting items above a certain quality in one slot and the others in another.
The typing would, again, go specific (shirt, pants, piccolo, broadsword), super (clothing, instrument, weapon), general (craft, item).
The overall goal would be to make it possible to tell how much of one kind of thing there is without having to add up a dozen individual entries, regardless of whether one is looking for crafts made from bear parts, footwear, tallow, unprocessed inedible plants, or dark grey stones.
