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.

Please add a search option to PDF Viewer.

It will be great If you can also add a thumbnail preview option to view all pages in the PDF and a page slider to help navigate user to any page in seconds.

Support for FileDocumentSource

Implement import of documents containing Type 3 fonts.

Expose a document loaded event

Currently, importing a document with non-embedded TrueType font will result in a font instance with an empty font source. Support should be added for providing custom font data of TrueType fonts during document import.

Allow programmatic navigation of the viewport of the PdfViewer.

provide an option for FitPageToWidth. The current option is to fit document to width.

When RadPdfViewer is used in a master-detail page, I should maintain the previous page index when I traverse between pages.
