pdflrf's landscape mode will divide the images into 2 pages. we can switch it back to portrait mode and sometime I think switch between those 2 modes is very convenient for readers.
I mean if pdflrf can make the output file in large size so we can use a simple way to switch between portrait and landscape mode as Sony's landscape function did, it's good.
And why you said Sony's landscape mode sucks? I feel it's ok for me.
