Oh yes, I forgot about that.
And I agree, I don't like unlimited inventory, is less realistic that way. I like the daycare/ranch things for fuzzballs. And I still say for banks, it should only be for money. As for items, I was thinking that maybe there could be something like "Item Holders" or something in various places around the world, but not always near a bank. Every city/town/village might end up having a bank you can freely get your money from, but maybe not every town will have an Item Holder.
Another idea is that some IH's could be out in the wilderness, but you must pay to use them, and even then, you can only get so many items over so long a period.
Runescape has kind of a semi-endless inventory in the fact that you have 28 spots to carry items, and some items are stackable, like feathers; and many items that aren't stackable, can be "noted." Very few items cannot be noted (obviously including items you can stack), so those must be carried individually.
