Thanks for mentioning that. I notice this too and it bugs me. I've tried a few different layouts and positions for those navigation buttons and so far haven't found anything else I like better. My thinking at the time was that most readers aren't quickly paging through chapters so it's not a key affordance. I'll probably do some site tweaks after I finish the last chapter. In the meantime, the layout is quite responsive. If you make the window narrower, eventually you get to a single column layout with the navigation statically positioned on top.
