Upgrade StorageFR: Improved thumbnail view
Thumbnail view for PDFs should work exactly as it does in Preview for Mac; as I scroll the PDF, the thumbnail pane should scroll along, so that the present PDF page is visible in the thumbnail pane (the reverse should *not* be true, of course). At the very minimum, the thumbnail pane should not scroll back up to the first page every time I navigate away from and then back to the thumbnail pane (e.g. I momentarily switch to the highlights pane).
