Have you done anything cool with Maps?

I am working on trying to leverage Domo's maps and a heat map that shows sales and revenue by Zip is nice, but I need to go a little further.  There doesn't seem to be much else to do with their maps.  The out of the box is nice and sure I can drill down to the county, zip level.  But you can't add a series, you can't see how one channel is doing vs another channel in the same "area".  Unless I'm missing something, which is entirely possible

Have any of you done any customizations? Made any apps?  Something that's taken Maps to the next level for your sales departments?
