[imp] Idea for new feature: View Only...

[Eric Gorr]

This is a common feature found in other popular e-mail applications, like
Thunderbird - the ability to display only certain kinds of messages in a
mailbox.

This could be a popup menu containing the same items as the 'Select' menu (well,
there is no need for the 'none' item).

So, for example, when viewing your inbox, you could select View: unseen and only
the unseen messages would be displayed.

This could be largely thought of as a more generic implementation of the
Show/Hide Deleted messages feature.

Anyone else like this idea? Is it already on the 'to do' list?
