What challenges did you encounter, and how did you overcome them?

Putting all the components together with react-router was a challenge, as this was my first project using it from scratch. I am not sure if I did it correctly, though. If you see something I did wrong, let me know, please!

I had some difficulty implementing keyboard accessibility on a non-static React component (pop-up section for region selection). I am not totally happy with it, as I wanted to circle through the selection and re-focus the open/close button when the section is closed.

What specific areas of your project would you like help with?

Any suggestions on improving the code and design, especially on how I used react-router, are highly appreciated.
