Recently noted a change in the way panels scroll. They used to scroll horizontally (press right to advance a page or left to go back a page). This was very helpful since any notes or citations would appear at the bottom of each relevant page.
The update now scrolls vertically and I need to tap on the note or citation to see it. In addition, the syncing does not seem to work properly or consistently.
I much prefer the old horizontal scrolling and hope you will consider re-implementing.
