Looks good, I added the snapshot tests to the step_* tests as well to make sure the step is actually surfaced and scanned through those manually. Also resolved minor conflicts with dev branch and merged it in.

Wasn't quite ready to merge this one, I have a few comments. Can handle in follow up PR.
