When GLR is performed and a primary key is automatically selected, perhaps we should prefer the non-null roles, and the smallest amount of roles under a relevant uc. To prefer similar sets, we could choose for the oldest (as in lowest role numbers). |

|
Instead of using the term "Primary Key" (which is a database implementation term) the more generic "Preferred Identification" should be used. This would allow the change of current PK when transforming to use the "Preferred" instead. Which, by design, may be outside an OT. |

Also: When 'generate artificial key' is set, the UC on the roles are no longer really required. The consequences need to be discussed and investigated. |

The UC Dialog now collects UCs inside the selected OTFT, but also checks for groupable roles and UCs related to those OTFTs. |
