Having a more sophisticated Album Navigation in Sidebar

Hey Everybody!
I have a little question and didn`t find anything (yet) using the search.
I want to have something like this in my sidebar

-Heading 1 (Gallery1)
+Album1
+Album2
++Subalbum1_2
+Album3

-Heading (Gallery2)
+Album4
+Album5
.
.
.

this navigation should stick there all the time, no matter on what picture or what not i click.
>> okay figured that out by adding the block "album quick links" to the sidebar section but is there a way to style this properly? i`ll let you know when i figure this out...

But the main problem still is that i don`t know how to create the second heading - it don`t need to be a seperate Gallery, but this would be nice because then, the second heading could be generated jsut like the first is...

Any help would be highly appreciated!!!
Thanx a lot in advance!
johimbe!
