THanks.
Is this a design feature?
Is there any intent to expand the capabilities at some point in the future?

I'm interested in using Showkase, but am not clear as to whether it supports
an arbitrary hierarchy of pages. AFAICT from the Demos and the documentation it doesn't seem to.
My current existing site's top level has links to 5 subsections, and each of them has a
mixed group of Galleries and Links.  The Links go either to a Gallery, a set of Galleries
or to another mixed group of Galleries/Links, and so on.
Am I missing something in your documentation, or is this functionality not supported?
