It would be really REALLY nice if while you are dead you could look at shops and sort of plan what you might want to purchase.
IMO this would help new players a great deal.
Looking at the shop while you're alive and not at physically at the shop, while initially sounds like a good idea for new players it might also be confusing...
What's to stop you from wanting to try to purchase something? How do you know when you're really at the shop Vs just looking?
