Double issue of ALA, with a search engine in Perl, and a backward compatible stylesheet switcher. “So what?” you say.
I’ve been personally waiting for this styleswitcher not so I can “skin” my site, but so I can offer a large type version. I’ve long suspected (from what I’ve seen in usability tests) that the great majority of people who need to make their fonts bigger have no idea how to. The stylesheet switcher could be used by a designer/coder to create a stylesheet where all the 10pt fonts were replaced with 14pts, and be indicated by a simple “large type version” button in a corner.
