1. Stockpile of fruits and cones
Just like the apples and flowers we pick from pots, the pears and quinces, the blue and strawberries could be stockpilled. There is a reasonable ammount of food and curiosities made out of cones and from my experience we need to take a floor of tower or build a house to store the cones and fruits you get from treefarming, diferently the regular farming in wich we can easily stockpile the goods near the cropland or store the seed into several places (bucket, barrels, granary). I beleave this would improove the treefarming experience, just like the pea and cucumber farming got much better after they became stockpilable.
2.Butter in barrels
It's true that one would want to be making butter when its needed instead of storing lots of it into barrels, because the quality of both milk and Churn constantly raise. But some of us already choose to store milk into cisterns, in this case we wont alreays use the best quality possible. If we could store butter into barrels, 100 liters to 100 kg, we would be able to choose between the strategies just like we already do with milk and other liquid goods. And it would be way easier to cook the delicious food available.
3.Taming Fox and Wolves into Dogs and Hounds
How nice it would be to have dogs for hunting (from the wolves that are comming soon) and for guarding the claim/village/area around its house. Dogs fed with raw meat and with it's quality improovement based on tics or petting or hunting, also having the its quality as base for its fighting stats like such as damage dealing, attack speed.
4.Ducks and Magpies as Poultry
The higher q fine feather we can have are the ones from swan and golden eagle. We already have a mailbox, maybe we could have a magpies delivering small objects and parchments to them! Also, the ducks we have would maybe fit well in a house like the ones with Hen, Cocks and Chicks, or maybe in fenced ponds, built from quicksilver, stones and lots of water!
