A couple of sidebar issues.........
Hyperlinks - I can't see how to highlight links and email addresses with the primary colour. Your demo sites for Profound and Decent display highlighted llinks in the sidebar but these disappear as soon a the Style Switcher is deployed. Plenty of examples on my 2 sites (Profound and Decent respectively) eg:
http://treadsoftly.net/sustainable-development-goals/
http://waitingtocreditmarvels.net/january-2012-curious-month-oxfams-woes/
Archives widget - the title "archives" is duplicated in the wordpress standard archives widget. See the 2nd example above.
