[followup to question on xcode-users list]
Just curious why you are using configurations. I've never found them to be useful for anything. My hope was that I wouldn't have to migrate some types of documents as often if the only entities that changed were not part of that document type's configuration. But that wasn't the case. All document types had to be migrated if an entity in any configuration in the model changed. So what are configurations useful for?

I use the same model for two different document types and would like to add a third. These each use subsets of the (default) configuration entities. I thought “addConfiguration” would give me a new screen with a copy of the original defaults, so I could delete what is not needed for each configuration and add other entities as needed. Apparently, it doesn’t work that way and I haven’t figured out how to do it.
