1. The same options available for items in inventory should be available in storage.
For example, clicking on consume for consumables should also be possible when among the features displyed for a house you've chosen to see its storage and there are consumables.
2. When moving items, either from inventory to storage or from storage to inventory, the option of a multiple selection of items might simplify a lot. I could think of donations as an example of the way it could be done.
