I miss more image and background options on the theme.

May be, full random image in the background or set full background image for each page.
One thing that most of the themes include is a Slider, twentytwelve could have an option for this and used un a page template, I´m not so fan of a particular custom post type just for the slider, is more interesting if the option can be choose the post to show in the slider and use the featured image on it, or select from media, directly in the image, if shows on the slider or not.
