Most of my attachments to Paperpile are in ePub format. He has superior readability for text. I read and annotate these with a Moon Reader in Android, but I miss being able to open them on the desktop for reference.
Thanks for the request, @Mzantsi - added your feedback to the relevant topic on our tracker. While our built-in reader can’t process ePub format at the moment, you can attach any type of file to a reference via the paperclip icon below the item in your library and open it from there in Google Drive.
Thanks. I’m not aware of any ePub reader yet that works with Google Drive.
