When I was reading one technical ebook I was wondered that would be good if I knew current chapter, session, etc. So, I'm filling this for ask if you can accomplish it. My idea is to have a space in the top that appear when the PDF have chapter informations. For example, suppose I'm reading one book that have this structure: Foreword 1 Chapter 1 10 Section 1.1 11 Section 1.2 17 Section 1.2.1 18 Chapter 2 25 Section 2.1 26 Section 2.1.1 26 Section 2.2 35 Now when I am in the following pages, the displayed breadcrumb would be Page Breadcrumb 13 "Chapter 1 > Section 1.1" 18 "Chapter 1 > Section 1.2 > Section 1.2.1" 25 "Chapter 2" 26 "Chapter 2 > Section 2.1" 27 "Chapter 2 > Section 2.1 > Section 2.1.1" See that on page 26 both section and subsection started. My point is to display the first one, I don't know if have some standard to follow. Hope you like. And thanks for this awesome piece of software.
