@mhidas happy for you to proceed with this one. I'll start a new branch for future pull requests ..

[mhidas]

@leonardolaiolo This is a quick & easy one to review. The changes are actually from @mphemming but I can't merge it without an approving review, and GitHub doesn't let me request a review from him... (Let me know if you'd like more context)

[leonardolaiolo]

Done @mhidas - I'll leave it to you to merge then.
