I like this tool, I'll definitely give it a go once the bugs are worked out.
I've also wished that this functionality were built into the Project Explorer. When a new class is generated and the inheritance assigned, we would see the static parent class method VIs already populated in the child. The VIs could be grayed or italicized to visually indicate that they are inherited methods. These wouldn't need to be actual VIs stored on disk, just visual pointers back to the parent methods. We could also have dynamic dispatch VIs come in as italicized and red font or something to indicate they can be overwritten...
