Yes, you are correct. The shortlist responds just to screen resolution whereas we put a few extra conditions to the responsive design for the playlist. Because the playlist already has a way to minimize the side panel, we chose to keep the same basic layout for all desktop views as most users will not see a smartphone size screen on their desktop monitor unless the app gets embedded in a smaller webpage. If the app is embedded, the app will automatically remove the banner to provide more space. Additionally, the playlist checks to see if the app is on a touch device (tablets and smartphones) before adjusting to a smaller gesture-friendly UI.
