Letterbox is a plugin for Apple’s Mail.app that takes advantage of your widescreen monitor. It rearranges the interface into three vertical columns –so the message pane is to the right of the message list, rather than below.
I just installed this, and it’s pretty darn good – like “I can’t believe Apple didn’t come up with this” good. Go check it out!
