I've put together a "pull request" in GitHub, https://github.com/oldfartdeveloper/PhotoGroove/pull/1, describing some "upgrades" that I've made to your Chapter 5 stage of the Elm program PhotoGroove.

In particular, I'd like you to consider my alternative to your Three Ints vs One List of Records outcome; I think you'll find it interesting, perhaps compelling.

That I've gone to all this trouble is a testament to how much I like your book and your publications in general; I find them both well-written and useful. I hope my suggestions help.
