We've all been there: you have the Dock set to auto hide and you miss the Mail.app notification telling you there's new mail. Well, don't miss that presidential e-mail again with Mail Unread Menu. This little app sits in your menu bar awaiting your e-mail.
This menu bar application can replace right-clicking on the Mail.app icon in the dock. You can check for new mail, compose a new message, and view the new messages broken down by mail boxes. This application did, however, seem a bit laggy in updating the unread mail count.
You can download Mail Unread Menu 3.1 for free (donations accepted) by visiting the developer's website.
