Hey, thanks for the PR, we'll take a look soon. You can run make style to ensure the linter & formater are satisfied.

This doesn't look right, we should only introduce order and then treat None as "does not exist" / "don't show".

[georgesittas]

I'll get this in and take it to the finish line. Thanks!
