For the record and I don't know if this is how other people have it...
I have a parent style that is the master style...all modifications and new templates go in here. I then create child styles with colour specific tones, but no template mods unless needed, thus drawing from the master...I was using one such child style during the install.
I just read the install and didn't see it...sorry, then again I didn't read the whole thread either, just grabbed the latest release and followed the link to here.
