Would it be possible in future release so that when you print the PLOG in the briefing pack and print it 2 up on a A4 (so two A5's if you see what I mean) to add an option so that the right hand side next to the PLOG is always  blank with just the ruled lines? This as others point out is useful for note taking info/clearances etc from ATC. 

At the moment if your plog fits entirely onto one side of A4 then the right side is then filled with your enroute charts thus no where to make notes. If the plog does over run onto the second page then fair enough you get the ruled lines beneath and usually enough space for notes - this option is just to force a blank page on the right when the plog fits entirely on the left.

My thoughts are just to try and reduce page turning when the briefing pack is clipped to an A4 knee board.
