Most PDF Viewers come with the ability to print, email, text etc the PDF that is loaded. For example, in the default iOS PDF viewer there is a "share" icon. When the "share" icon is tapped, multiple options and apps come up that allow users to "print", "message/text", "email" the PDF. It would be a great feature to have in the Xamarin UI PDF Viewer. It could just be part of the PDFViewer Toolbar options.
