Shorthands in QuickEdit for Fast Modeling

Now QuickEdit is extended with many shorthands used for creating elements quickly. When you want to create a sub-class, for example, you have to create a class and then create a generalization by connecting the two class. Now, you can do this by just clicking "Add Sub-class" button in QuickEdit at once. This feature allows you to build a model very fast.

Sizing Elements Equally

Three menus for sizing selected elements are appended in [Format > Alignment] menu and Style Editor. "Set Width Equally" sets widths of selected elements equally and "Set Height Equally" sets heights of selected elements equally. "Set Size Equally" sets the both widths and heights of selected elements equally.

UML Improvements (Receptions and Internal Transitions)

Now you can create Receptions in Classifiers and Internal Transitions  in Composite States. For more information about Receptions and Internal Transitions, please refer to UML Specification.
