A quick feature request – it currently seems that I have to use the mouse to scroll horizontally in MetaPDF. It would be very helpful to be able to scroll horizontally with the arrow keys. I often read documents with multiple pages or columns that require horizontal scrolling, and it’s a little annoying to have to grab the mouse each time. (I also recognize that this might be an issue with Chrome, not Paperpile–so any workaround tips would be appreciated.) Thanks for all your work!
I had a look at the problem, and a fix will roll out with the next release of the PDF Viewer.
