Comment 5 for bug 708457

I talked to Crystal about this alot, and I figured out the use case. Let's say she is cleaning up her mailbox. She would sort by sender, and then go through the huge list of emails selecting large groups of emails all at once based on their sender, and delete them all at once. The reason search is less practical for that, is she would have to search over and over and over for each sender she wants to purge. That could get VERY tedious.
Tell me if you need a better explanation....
