So, for textbook reading often I have to refer to a diagram and text at the same time or want to look at different pages or sections of different pages all at the same time. If it were possible for a reader to have advanced viewing options so that I can just snip the diagram and it becomes a floaty window and if I want a set of pages to refer to I can just select and put them somewhere for easy navigation (page holding) between relevant pages of the same 1000 page book. It would be very convenient. Thank You.
