I hope I do not post this out of naivety, but it seems that when I drag a piece of mail into a folder, it moves it there rather than making a copy of it there. I would like the ability to still have the message in my Inbox, while copying it into a certain folder.
Oh, and I'd love the ability to make filtering rules, ala GMail (I'm sure I'm the umpteenth person to say this, which doesn't make implementing it any easier).
