I love the coloring on either side of the Sales Amount slider! This might be a terrible idea, but I wonder if the position of the handle could also reflect the relative values of the data, rather than being linear? So the slider would be informative on its own. As I say, perhaps a terrible idea, but thought I'd share it :)

Is it possible to make the grouped select box allow multiple values to be selected? Awesome stuff in this notebook btw.
