I have been using MetaPDF as the default PDF viewer/annotator in Google Drive. With the release of the newer version of the PDF viewer/annotator in Paperpile, which is a lot more capable, I switched to using it as default in Paperpile, but it is not available outside of Paperpile, so I continued using MetaPDF in Google Drive.
More recently, I noticed that MetaPDF stopped working in Google Drive (does not open PDF documents at all).
Can someone comment on the strategy of Paperpile going forward? Is MetaPDF abandoned? Is there a plan to have the new annotator available outside of Paperpile? What should users expect?
