Attribute Assistant, part of the utilities template stuff, is a remarkably good idea that in no way is limited to utilities. In my way of thinking, functionality like that should have been available long ago. And I certainly shouldn't have to go hunting through forum posts & blog entries to find the addin files and documentation for it. This stuff needs to be included in core ArcGIS functionality. And rather than being managed with config files I can't find, I feel strongly that I should be able to manage this stuff with geodatabase properties-esque dialog in ArcCatalog.
