My apologies if this has already been posted.
I wish we could (and if we can now, I'd be happy to be corrected!) have a document hierarchy, but select in a view construction where to start in the hierarchy.
In other words.....I have an application
where each layer is a response to the previous layer. Now, if I want to show documents in a hierarchy, I can't simply say "form=Task & @allchildren". I can only show the document hierarchy if I start at the top of the hierarchy.
