The app does remember where you left off when closing, but a proper bookmark feature is needed. If someone has to jump to the index, or skip a few chapters, and wants to come back to a specific spot then bookmarks are the way to do it.

A much-needed feature! This would make possible to add notes in books. Besides, it is a very important tool for preparation of academic papers.

I.e., it would be great to be able to mark the text (or just specify the position in the text) and write down a comment. And to have a list of comments + highlight them in the text.
