Feature request: Add page turner and annotation histogram to PDF view

PDF not rendered to pages / flip view.
I don't know if this is a feature, but perhaps it should be? When I upload a PDF it is currently displayed in a viewer that allows annotation. I miss the oversight/header of annotation denisty, and the page flip. Reading the PDF becomes difficult on mobile devices.

Thanks for the question and the feedback! Because it's a new feature, the PDF annotation does not yet support the page turner or the annotation histogram that HTML text provides. I'm going to convert this into a feature request.
