View multiple mailboxes in single pane

Apple Mail allows you to unify all your email accounts under a single Mac interface. This makes it really convenient, as you can read and reply to your Gmail, Hotmail and other assorted email accounts from one desktop application. But did you know that you could view all of the email from all of your email accounts in the same pane? Here’s how.

Sometimes you will wish to purposely view each of individual Mail accounts separately and you can do that by simply selecting any individual Mail account or email folder in the sidebar.

At other times, it may be advantageous to view all email accounts or a combination of email accounts — or even a combination of different email folders or RSS folders in one big pile. To do this, simply Command+Click each email account or individual mail folder and the contents will be combined into the one viewing pane.
