The best aspect of the infobox previewer is that its functionality can be abstracted to support just about any feature because it separates the markup, from the css and the invocation.

So it could be renamed and repurposed as a " [portable] feature previewer" and could support things such as navboxes, sideboxes,  notices, and so on.
