I've been looking for other utilities that provide the function of renumbering fabrication parts.

Bad news: I can't seem to find anything but the Applied version. There are lots of other renumber tools out there, but apparently they are limited (I'm assuming by the API) to only certain types of categories, and the fabrication parts are just too new for developers to focus on it yet. 

Good news: Based on the comments here, reviews and such, it looks like Applied did their job well in developing this utility, but only time and use will tell.

Now if only I could get a copy of it... hint hint
