Could you add a way to make the actual borders of PDF docs visible in Light Mode, either by another background color than white (preferably adjustable by the user) or at least a faint border? Since I can’t see where a document ends I frequently hit the edges while editing.
Also: For editing purposes it would be great to pan a zoomed-in doc more freely on the “canvas”. Why does it have to stop at its borders? That makes writing on the margins more difficult than it has to be.
