You can rotate the pdfs in the Edit Mode [edit>files>rotation] { auto rotate may help if available}; set up the page turning in Settings>Touch and Pedal Settings; and the 1/2 page/page in Display Settings [4th icon from the bottom left, Edit Mode] and there are a couple of pertinent settings in Settings>Display Settings. The scrolling style is in Edit>Scroll Settings [triangle in a circle icon].
You will probably have to play around a bit to see what works best.
