Kindle Family ncx Treatment

I'm seeing different treatments of the ncx across devices. The Touch shows entire list (a la ePub); the Fire, the iPad App, the Mac app, show the traditional 'cover, beginning, location, etc.' lineup. However, the Touch also adds hierarchy where none exists in the ncx. And, Kindle Previewer for all of these devices show the full list, but not in hierarchy.

What's going on?

This feature showed up with the 5.1 update for Kindle Touch about six months ago. It is also on Kindle Paperwhite now. New features take awhile for Amazon to propagate to other apps and devices. I think the new Fires may have it also, but I don't have one and they have not posted a User Guide yet, it appears.

Kindle Previewer has NCX navigator because they needed to give publishers a way to preview that content, even before a given device or app supported it, so that when they add the feature, the navlist will display properly. I submitted a book a couple of years ago and finally got to see how the navlist looked on a real device six months ago.

thank you for the details. it helps a lot, and will help with client's concerns

On older Kindles, there is also chapter navigation feature that only happens when there's an NCX. So even though the navlist labels may not be visible, it is important to have NCX, and have the labels be what you want for devices that have a navigator.
