Request for feature: Tree of mailboxes

["Sergey V. Udaltsov" <sergey oudaltsov clients ie>]

Hello all

Thanks to all Balsa developers for 0.9.5. This is almost
nothing-more-to-desire lightweight mail client. I think it just needs
one touch to be the one: tree of mailboxes. For example:

Inbox
Outbox
...
Friends
  Johnny
  Kate
  Max
Mailing Lists
  Gnome
    Balsa
    Evolution
  Java
    JavaWorld
  IBM
...

etc.
Is it difficult to implement this? Certainly, filters should be able to
store the message to these boxes...

Please do it before 1.0 release!

Thank you very much for LDAP support - this is simply marvellous!

Regards,

Sergey V. Udaltsov
