I've watched people who aren't at all familiar with storymaps navigate some storymaps developed with the new template, and more than one person reached a sidecar section of the storymap, and thought that was the end of the story.
If there were some way of either making it more obvious that the user needs to scroll, or making the sidecar smaller (so it is more like one of the embedded maps, where it is more obvious that you can keep scrolling), that would be great.
Many thanks,
Helen
