I don't know if Im missing something, but I installed the devtool, I open it on a theme I downloaded (the index.htm file opened in firefox, with all of the accompanying js and css files in their proper directories) and it is unusable. The accordian tabs dont even open, so it literally is just there for decoration. My assumption is that when you open it on a page built with theme roller you are supposed to be able to use it to tweak the theme? Please tell me if I am missing something.
