I'm sure it was great, but always beware to change two similar codes into a more generic one, when what was originally two served two different parts of the system. In that case, what can happen is once the requirements change for one part of the system, now you must change a generic component in such a way as to not disturb the other part using the same component. That way madness lie. (Of course, cut-n-paste programming is also madness inducing.)
