One Page Option

Hello,
I really love the live preview of the book / ebook on the right side of the screen. It helps a lot with how I write my books!
But I am wondering if there is an option to view it one page at a time. Right now, we're unable to zoom in on the preview, which makes it hard for me to read my text. I'd have to either squint or pull the screen closer to my face. Adding the option to view one page at a time would really help! Thanks!
