I use the notebook to present to clients. As I'm a designer I like to ensure every pixel is perfect. Unfortunately when I try add an image to first page it adds a drop-shadow and also a duplicate image to the bottom of the page which ruins the look of the page. With no option to change CSS or switch this off it has become a bit of a thorn in my side.  I suggest having more customisation options on the notebook or at least switching this off as most people know how to manually add a drop-shadow to an image should they require one.
