I would like to be able to sync my PDF’s to Dropbox instead of Google Drive.
I already pay for Dropbox and have plenty of space. I do not want to have to worry about expanding my Google drive storage.
I use Linux and Google Drive does not have good integration with Linux. I can’t really make local annotations to the PDF’s have those annotations persist.
The Adobe Acrobat PDF reader for Android has Dropbox integration. Annotations I make on my tablet are immediately saved to Dropbox.
I switched to Paperpile from Mendeley almost entirely for the Google Docs integration, but I don’t like the way the PDF’s are being handled.
