Moveability of the virtual page on the virtual background would be a huge banger. Maybe even rotation to fit to the user natural hand allignment on the page.

Why?

I ALWAYS have that huge problem on the lower part of every page. Cant access it porperly because of the rim of my iPad. It gets worse with my confuguration because i have heavy duty case (work in industry) which thickens the iPad alot.

ofc I would have the same problem with normal paper or notebooks.. but we could have that option, right? :D
