Thank you for this wonderful plugin.
There seems to me a small bug with the front page. If I use [autonav display="images,title,thumb,excerpt"] in some page it works correctly. But if I define this page as front page every sibling of this page is displayed too. I have been avoided this by defining an empty front page which is redirected to the former page. This works.
Perhaps you can fix this bug in the next version.
All the best
