This is definitely the most-oft-requested feature in the comments so
far. Presently, I don't have the technical acumen to pull this off,
but I do plan to eventually produce GeoJSON for the map as an
auxiliary resource, which would certainly be a step in that direction.
I'll have my eye out for hints and help for this in the upcoming
year.
In the interim, I'm planning to do a similar, but probably more
pressing feature: I want to make a sort of slide-show that traces the
route followed by the characters by each story. There would be
navigation (prev / next) at the bottom with (hopefully) ancillary text
in the article box on the top-right for each location.
I've also made some progress on incorporating quotes from the book at
each location, but that project will require significant further
development.
