So when giving your vote books to your ironman alt you have to do it 1 by 1. If you've stocked up on loads then this could be a real pain in the butt!
So, I'm suggestion "Give All" option so you can give the whole inventory of books instead of 1 by 1.
Place it underneath the 1 x - I'd also suggest having to confirm it again afterwards so it would ask "Are you sure you want to give all your books?"
Something Sheep didn't suggest but I thought of myself: If the person's inventory is the full, the person receiving the vote books, then the ones which can't fit into the inventory should be placed his bank.
