Finding attachments is too hard. Most emailer users have the poor habit of copying the entire growing thread over and over. The result is a bunch of cat vomit with the attachments like hairballs along the way.
Implement some UI feature that parses out the attachments, removes duplicates, time sorts the unique ones, tags each by sender, and then allows this attachment chooser to appear at the top of the thread, at the bottom of the thread, in each message of the thread, in a separate pane outside the conversations in the top of the screen, bottom of the screen, left of the screen, or right of the screen.
Having to be in email at all is bad enough -- don't make it horrible by making attachment retrieval a messy business.
