This is perhaps not the first time this has been suggested:

Can you possibly expand storage space at Winery? I'm constantly overloaded and while crafting find it difficult to store everything. I understand all my options as far as upgrading bags, clan storage and teleport. I waste so much of my game time rearranging my inventory. It is kind of silly.

In you great benevolence can you find it in you heart to do something about this terrible affliction?
