One thing we could do with is some plastic grid style matting to raise cups and mugs off the bottom of the cupboard. That way, even if the mugs are a bit wet when they go from the dishwasher to the cupboard, they'll dry properly instead of smelling rotten inside. It's only happened once as far as I know, but when I found them like that I had to empty the cupboard and run them all through the dishwasher again.
