@Mugen87 I am unable to successfully create a screenshot for some reason. Can you please give it a try?

[Mugen87]

I wasn't able to push to your branch but here is the updated screenshot. I hope GitHub does not further compress the image.

Thanks, @Mugen87, but e2e is failing... Trying to figure out what is going on. :/

[WestLangley]

@Mugen87 You screenshot may be compressed. It is not passing e2e. And my screenshots are black.

I wasn't able to push to your branch

Not sure why that is, either. It says "Maintainers are allowed to edit this pull request."

Now it works! I guess I was on the wrong branch, not dev-clean_up.
