The new mail is great, and so is Lion as a whole. However, I wish apple would have finally added my outgoing mail to the conversation threads. This need seems even more evident now that they have the conversation view. If you have a long email chain between you and someone else, the conversation view doesn't look like a conversation at all. It's just a big list of all their emails. You have to click show more to see what I have said, and with it you get the gross formatting. It sure would be nice to have outgoing emails added into the conversation view chain. Maybe a third party plugin can take care of it, because for the longest time Apple has seen no need to add this.
