Show the book name that you are on in the middle of the dropdown list

When you are using the option to list all books by full name in a long list (which goes off the viewable page), it would be nice that when you click the book selector the current book you are on would be shown in the middle of the list and be highlighted. This way you would know the immediate context of the books before and after the current book without having to scroll. Right now if you are reading in the NT and you want to go to a different NT book you have to scroll through all the OT books.
