Thanks for the PR!

I am not the best to review this code but .DS_Store definitely shouldn't be committed :)

[mrnugget]

Looks good to me! But, as @unknwon pointed out, please remove the .DS_Store file from the diff 🙂

[keegancsmith]

@stephen ping :)

[stephen]

Thanks for the reminder. I removed the .DS_Store and rebased to fix conflicts. I tried to match the changes in f935979 in my new diff.

[stephen]

Separately, adding .DS_Store to a .gitignore might be nice.

Thanks!
