Hi,
I noticed that when I open papers with the paperpile button (e.g. when I have already downloaded them), I get redirected to the legacy paperpile viewer, even though I set my default viewer to be the google drive viewer. I then have to go to paperpile and open the document again to get the google drive viewer (which I only use to quickly get to meta-pdf). All in all a bit cumbersome. Would be great if the app button respects the defaults set inside paperpile.
