Nested albums

Hi

It would be nice to have support of nested albums.
like: "My Holiday 2010 album" -> "First trip to Australia desert album" -> "Day 1 album" -> "spider image"

it will make sense much more for albums out of User's main album.

E.g. my gallery structure (using gallery menalto) has two main galleries.

The first was "Photos from site events"
It's structure was:

-- Photos from site events
---- 2010
------ Cooking Event on boat
--------Gallery1 (Photos from Michal)
--------Gallery2 (Photos from Peter)
--------Gallery3 (Photos from Jane)
--- Dating event in the park
--------Gallery1 (Photos from Michal)
--- Drinking event in the Pub
--------Gallery1 (Photos from Suzan)
--------Gallery2 (Photos from John)
--- Dancing event on the boat
--------Gallery1 (Photos from Michal)
--------Gallery2 (Photos from Peter)
--------Gallery3 (Photos from Martin)

The second main gallery (in gallery root) was User's album. It contains entire user albums (I described it here: http://drupal.org/node/916220)
the structure of this gallery was:

-- User's galleries
---- John's gallery
------ My daughter's birthday
------ Our Holiday 2010
--------Spain
--------Portugal
--------France
---- Michal's gallery
------ Summer Prague
------ Winter Prague
------ Charles bridge

thanks
