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.
Thank you for your idea. The status of this idea was out of date. Since this was requested we have made improvements to the slide editor. Images can now be added directly to slides and do not include drop shadow. The images are also no longer included as files below the slide (which was the cause for the duplication noted in this request.)
