Currently, sorting can be done by info columns about the various e-mails in a
folder.  Sorting by any one column does not guarantee a unique ordering of
e-mails.  (7 columns only provide vague categories such as read/unread) Because
of this, there is room for the resulting sort to not match the user's expectations.

As an example of what I personally want to see when I click on a folder:
1.  All unread messages
2.  All labeled messages (ie. important first, then work, then personal)
    (Most recent messages first)
3.  All other messages (read,unlabeled)
    (Most recent messages first)

The sorting criteria for this would be
Primary Sort: Unread
Secondary Sort: Label
Terciary Sort: Date


Fixed Number of Categories:
Read:            2 categories
Status:          4 categories (at least)
Flag:            2 categories
Label:           5 categories (by default)
Junk:            2 categories
Priority:        5 categories
Unread:          2 categories

Other items that might benefit from secondary sorts:
Thread, Subject, Sender, and Size (if quantized well)

Unique sorting criteria's (ie must be last criteria applied)
Date, Order Received

Reproducible: Always
