So, the one gripe about stockpiles I have (assuming you don't pre arrange them) is that you can't really tell what is in it other than that specific type of thing, rocks, hide, etc. I was thinking some option would be nice like, the hide stockpile for example, let's say it shows it like it currently does where you have x/30 hides in it, maybe there could be an expand button that shows how many of each different type there is, so like horse hide: a; dried horse hide: b; boar hide: c; etc, but only show these additional hides if that type of hide is actually in the pile.
I was also thinking, and even just this option alone would be great, an option to sort piles by highest qualities on top or lowest on top, depending the button pressed. It would be even better if you guys could get it so say in the junk pile when you press this button and you have, let's say entrails, intestines, and feathers. it would sort the highest by each item (assuming you actually implemented my first part of this suggestion) where the highest feathers would be on top (in the expanded menu) and the highest intestines, in their respective slots.
Maybe I should make a sample picture to explain my suggestion better, but let me know if you want me to clarify anything or expand upon anything.
