Please allow an icon to access the principal index of the publication such as iBooks does. Usually I used this app with safari or iBooks, in the split screen for personal study and researching. But is very very difficult to find chapters, themes etc; specially if you has to jump form one place to other in the publication many times. I felt lost in a publication too many times, that makes hard to use this app. Despite this I like it and I hope developers are going to fix it.

Thanks for hearing us!
