Sorry if the title is a bit confusing but I'll try to explain it here. When talking with other users on walls, is there/could there be any ability to easily go back and see a list of the conversation in chronological order? This would make it easier to pick up from a conversation if it finished, or allow you to go back to earlier conversations and understand the context within that conversation without fanning about on other users' walls and checking dates to make sure that that specific wall post is a part of the conversation you are reading.
