I agree, that if I have one wish I'd wish for an inventory search button. Take that back, I need two wishes, since I also need gem confirmation button.
And we all know that we've begging for these two things in vain since forever.
Tips: If you need to find something from the storage, it helps if you know whether it's a deco or building since the building tab has a lot fewer stuff. I'd get it out, place it, then store it again. That way it'll be at the top of the inventory page and I can just get the second or 3rd item or all of them out.
