Thanks. Yep, I sorta figured it out by reading through the other forum messages. So, to get this to work, I need to put a separate javascript REFRESH link AND style=moi.css?v=1.1 (temporarily) into the following files (so far....)

SidePane.htm
BrowserPane.htm
CommandBar.htm

Don't know, but there may be others..

I don't suppose there's any sort of 'mapping' chart of CSS to the UI anywhere? I looked around and all I found was:

***for those following along. PUT the previously mentions style=moi.css?v=1.1 at the TOP of the head, not the bottom. You don't want to override the custom styles in the htm file.
