Very nice program. How hard to split screen so you can see the changes to the map as you make changes below?
Yeah, I saw that was an annoyance as well. I’ll see what I can do this afternoon. Web programming isn’t my cup of tea - this was built by hacking at an open source US map app.
Split screen should be there now, thank you for the suggestion: https://joeisdone.github.io/predictor/
