Hello,
I suggest what the players have more basic space in the banker, for storage non stackable things.
For example the stack of souls can be convert into a stackable stone, very good and thanks. But the dust (armor and weapon) can not do it yet.
Other solution it is make the dust into other stackable thing, as dust in a bottle(?), dusty rock(?) any name is good while the item will be stackable.
Please accept this suggestion as soon as possible.
