[MlMt] Hide "Default" Mailboxes

[Pedro Lobo]

Hey All,

Been AWOL for a while and finally decided to return to our beloved 
MailMate. Having used a plethora of simpler email clients, I’ve become 
accustomed to a little less visual clutter, in particular with regard to 
mailboxes in the sidebar. I can’t quite recall if this has always been 
like this or if it’s recent, but either way, I’d like to know if 
it’s possible to hide the default mailboxes such as Sent, Trash, Inbox 
from the Account list. These mailboxes are already accessible from the 
global mailbox list for Inbox etc. (is this making any sense?)

Cheers,
Pedro
