Today we launched a snazzy new tool that allows you to quickly scroll through the Newscoop themes and see them functioning right there in your browser.
The problem isn't the themes - it is the top frame with the theme switcher. It messes up the responsive layout of the themes and makes switching near impossible. It is very obvious - try it out with an assortment of mobile devices (some might handle it better than others, all my attempts with android devices and an assortment of browsers have been problematic).
