Saddle Pack

I think there should be some kind of pouch/pack you can attach to saddles. For example, you could attach the pack onto any saddle and ride around with some storage so your inventory doesn't get as full. It could almost be like a boat with a chest, being able to ride with something that you can store excess items in. The pack/pouch could be crafted with leather, then it could be combined with the normal saddle like you would craft a carrot on a stick.
