LGTM! Tiny comment about naming.

I find it odd that confusion matrix is not mentioned in the option name. Did you have in mind that it could be useful for other modules?

like cf_normalized?

Sold! FYI - I don't mind for the route that it's called only normalized - it's only in module options where it is mixed with everything else that I find it confusing.
