dovecot - Jan 2014 - virtual mailboxes folder structure

Hi, I am trying to find a way to list my virtual mailboxes hiding the namespace
prefix into my imap client.

Fore example now my ?All? mailbox is listed under virtual/ as:

Inbox
Sent
Drafts
Spam
Trash    
virtual    
    All

I would like to list as this:

Inbox
Sent
Drafts
Spam
Trash      
    All

This is my 10-mail.conf: http://pastebin.com/DumEbbmy
and this is my 15-mailboxes.conf: http://pastebin.com/QFzWGzyC

I thought that the list = children paramenter would do but it did not.

Thank you
