Simlpy having us able to place hay back onto the hay stack would work for storing it, the same gose for being able to take sticks to and from 'piles of wood' so long as they are not lit. Or letting us make bundles of sticks that we can store.
A block pile would be a lovely thing to have sitting next to the fireplace, it would be asthetic to.
Changing the plank piles graphic to show plained/mouldy would give is not only a nice storeage pile but would also give us visual clues.
Oh and PLEASE can we get a meat locker where we can hang our kills - you could even let the meat mature (or go rotten

)
Being able to store salt, feathers, woodchips in dry goods bags would be wounderful
And I adore the idea of being able to set up rolls of cloth.
Lastly, do you think we could get a sack for storage? Somthing that you can store in other containers when empty yet when it is needed - like harvist time you can set it on the ground and fill it like a normal container.
Do not argue with idiots, for they will pull you down to their level, then beat you with experience.
