I've made this new version of QuickWho substantially different from the older ones. It offers more information than a simple dump of whois output. It's easier to use and better integrated into OS X so it can be incorporated into different workflows. If a program is at a dead end and cannot do what you want it to, you may have no choice but to rewrite large portions of it, even the entire thing. With QuickWho, I rewrote major portions of the user interface (removing the tree view, developing and customizing the rich text view, adding the image display) and completely re-implemented the whois query, as well as the alogorithms to print the data (since it now included an image as well as text).
I believe the program now does far more than the simple command-line whois tool, and previous versions of QuickWho: it offers a richer array of information about specific domains, in an easier-to-read format. I hope you'll give it a try.
