Trading and sharing need a major over haul

The trading and sharing system is severely flawed and in need of huge changes. Right now if I want to trade with someone there is no way for me to tell what they own. Seeing a wish list only is way too limited. We need to be able to see a person's entire collection and how many they have of each card so we know what to offer them that they don't have and can figure out what we can ask for that they might be willing to trade. We also need to be able to actually talk to each other during a trade to facilitate this. If you are concerned for some silly reason about amking that visible then provide a toggle switch where people can block the viewing but then that person just won't get anyone trading with them since they chose to make it difficult to see what they might want.
