I wasn't sure which ProfitUI I should download, just went with the most recently updated, or at least, at the top of the list, which was indeed ProfitUI Maintained. Did you mean
this?
Taking the nav/exp bar as the example, from what I can tell, there is the left page and right page, each having west, center and east. Can you give an example based on that? I've studied basic XML, but this is a little bit new to me as it has a whole lot of different attributes and terms I've never heard of before.
