Based on feedback from customers, we wanted to create a new playlist theme optimized for width constrained situations. As a result, we're happy to announce the release of the Tango theme which can be seen below.
The Tango theme displays the list of videos below the video and allows them to scroll horizontally. As a result, the width of the playlist is the same as the width of the video.
Tango is a perfect complement to the existing playlist themes....Steam, for height constrained layouts (playlist to the right of the video) and Trim for ultra-compact situations (playlist displays inside the video).
