The inventory could be improved to have it that when you are checking a new item it compares with the one that is currently equipped which is a very basic feature in every RPG game. Also add the option in the inventory to be able to see only armors, consumables, weapons, etc would be very useful.
Also the storage in town should be improved, at the moment is very difficult to go though the items in the storage.
Here is how it is right now.
