I assume by collapse you meant more of an AJAXy "click a link and it collapses/expands in place" which would require JavaScript ( which is a big nono outside trusted mode ) -- Something like that could probably be done through S2 by having a link that added/removed arguments ( if you were okay with lack of persistence if you revisited the page w/o those arguments, because there would be no way to persistently "mark" the entry )
Re: :-)
http://bugs.dwscoalition.org/show_bug.cgi?id=3503 is the bug in question -- that would be totally implementable on the S2 level alone, just as a ?.arg as you couldn't define the new view.
