What is the enhancement in mind? How should it look and feel?
Was wondering if it would be possible to add a function to select or deselect all check boxes on the current page of your mailbox.

Please provide any additional information below.
I've been trying out an addon  called EasyMail (http://www.wowinterface.com/downloads/info11426-EasyMailfromCosmos.html) just to test out the differences between it and Postal. While I like a bunch of the features in Postal over EasyMail, the main being the ability to see whats in a mail with a bunch of attachments than just a number "(2)", EasyMail does have the ability to select all or deselect all check boxes on the current page of you mailbox. This would make it easier than having to tediously go down/up the list individually checking each box if you want to open or return multiple packages.

With the open all feature and the ability to Shift-Click 2 checkboxes to select everything between them this seems well covered.
