Need improved PDF integration with libraries in SharePoint Online. Microsoft posted an article in 2012 about improved integration support for pdfs with Adobe Reader. That was FIVE years ago and its terrible now. We need integration to function like it did in SharePoint 2010 but with Acrobat. It was aware of the library and all document properties. Allowed us to open files from SharePoint with out having to download them first. SharePoint is great but the incompatibilities with third party browsers and applications that wreck the user experience are why adoption is so difficult.
