"Blueshift" is technically in the works, but the templating system for site styles is so appallingly clunky there are just no words for what a PITA making and maintaining different site styles is.

Honestly, if the templating system could just be reformed to something sane, so the site always uses the same html, just arranged and/or colored in different ways as per style or user desires, it seems like that would fix so very many downstream problems. This one included!
