Something I think that would make the story map easier to use for readers is if the thumbs up icon turned blue for chapters they liked like it does on the page after it is liked. The reader can see the chapters they liked in the story map and as well as see any branches that have been added to the paths they like. They can come back to the story days, weeks, or even months later and pick back up on the parts they liked. Alternatively add bookmarks to the story map and do the same thing where a reader can see chapters they bookmarked on the story map.
This is a must have in my opinion, the reader would have an immediate and complete look at what he\she liked in the story (important especially in complex or big stories)
