If a chapter ends in the middle of a page, the next chapter should not start until you move to the next page. If a chapter now ends in the middle of a page, the header of the next chapter appears immediately after on the same page. This is not true with BD page breaks. If a chapter ends in the middle of the page, the remainder of the page is empty and the reader must page foward to see the next chapter.
If a page break is after the title page,the reader must page foward the see the graphic of the author. The same is true moving to the toc and from and from the toc to the start reading.
All of this is not happening with Creator except by accidental occurance of text. BD makes it very simple.
