Button for “read more”

I have just purchased and installed the pro version of Cool Timelines and am quite happy with the simple historical timelines I am creating. However, I have two concerns, one of which I’ll describe here, and the other under a separate topic. When I was first working with Cool Timelines, I noticed that the “read more” notice on a story was enclosed in a button or box. However, after playing with the settings, that button has disappeared and I see no way to get it back. Now, the notice is has the same font and color as the rest of the text in the story, making it hard for the viewer to easily realize that there is more to be viewed. How can I get back that button? Alternatively, would there be a way to change the typography of the notice so that it would stand out?
