Roki includes a great premium plugin - Revolution Slider, $15 worth, and gives you the opportunity to benefit from tons of unique transition effects, an image preloader, video embedding, autoplay that stops on user interaction and lots of easy to set options to create your own effects.

Thanks to the powerful bootstrap front-end framework, roki is not simply a responsive theme, rendering natively on all devices - mobile, tablets or desktop, but features a fluid layout.
