Kobo page fitting

After reading a lot about both the new Aura and the Paper White 2, I am about to preorder the Aura. My main hangup is that in every video you can see the book's title on top of every page, and a huge main at the bottom. I assume you can get rid of the title, but, can you format the book so that the bottom margin is reduced to a minimum? Are there any pictures showing that?

Thanks in advance.
