With the folder pane, the focus pane, the vertical conversations list, and the email preview pane, the Postbox interface feels busy. Fortunately, Postbox allows you to eliminate the folder pane by setting up a handful of favorite folders, which you can then access via a toolbar at the top of the window. You can also collapse and expand the focus pane with a single click, and even hide the email preview pane, so that you're left with just a minimalistic list of message headers.
Postbox isn't perfect, but then again, the same can be said about email itself as a communication medium. Still, if you're not happy with Gmail's browser interface and yearn for the comfort of the desktop clients of yore, you would do well to try it out. Be sure to allow for an adjustment period. Slick as it may be, it's still an acquired taste.
