Letterbox

Stop what you're doing and install this now!

Finally someone has come up with a way to view Mail.app with a vertical reading area. You know, like Outlook has been doing FOREVER.

Letterbox is a Mail.app plugin and it puts Mail.app into a three vertical column format - perfect for reading on widescreen displays. Folders on left, list in middle, email on right.

Thank you Aaron Harnly, much appreciated.

I use gmail more and more in Chrome on Mac and PC but with MsgFiler, copy and paste and IMAP you can get a lot done in Mail.app.
