Changed the "simple" theme to be a "standard OpenACS theme", by which I mean it uses the portal, portal-body and portal-header .CSS classes which are defined in our standard .CSS file. This gives portlets a look that's identical to the non-portalled standard OpenACS index page.
Got rid of the gross configuration page stuffed in the Tcl lib (!) and turned it into a proper template, modified the UI a bit while doing so, and made almost all of it work (though there's a few bits to finish up).
