What a refreshing approach to styling.
I haven't had to touch a single template (well, okay, apart from EXTRA.css) and everything has been easily achieved through the ACP and the Style Properties system.
Granted, it's still a recognisable XF board, but now it looks like my XF board.
Well done on creating a flexible system that is easy to use.
I understand the template conditionals offer an amazing array of posibilities too, but they'll have to wait until I'm less ...
