Hey Pete, 
first things first: great plugin. Now to my lil problem: It seems, that I can't get it to work. In the admin configuration for these plugin I typed the paths in correctly but It doesn't seem to add the new fields to it. 
Paths my JS/CSS are in: 
/dev/proc/site/templates/_sitejs/ 
/dev/proc/site/templates/_sitestyles/ 
Can there be a problem with underscores? Thank you for your help.
