heya... could you put this stuff on one page? I don't want to be a pest, but the chapter-format is kind of aggravating trying to get my head around how to talk to this thing.

You mean all of Section 5 on one page?  That would be a big page.  What you can do is click "Print all" or "Export all" at the top of this page if you want to see all of Section 5 at once.
