 - In diagrams, it is now possible to create a `SatisfyRequirement` from a `PartDefinition` or `PartUsage` graphical node.
+- In diagrams, many new tools now automatically select the `Elements` they create or expose on a diagram.
+This makes it easy to start editing newly created elements to give them proper names by starting to type directly when the new element appears.
