Since the addition of stacks most stockpiles have a bad item/space ratio, some were bad before stacks, but it's even worse now.
For example, a stockpile of bones contains max 40 items, a small chest full of bone stacks can contain 36x4 (144) items, and occupies less space.
Make stockpiles bigger. Just multiply all of them by 5 or something, otherwise most of them won't be viable to use once you get some metal to make decent containers, and having to manage your storage is not fun so why not make it easier.
And while we are on the topic of stacks and stockpiles, why the hell can't you make stockpiles using a stack, or input stacks directly into stockpiles. That would also make stockpiles a bit more usable.
