Describe the solution you'd like

For example, in use case diagram, when we fill a use case, we cannot choose if we agree or not with the automatic line return. And for an actor text does not return to a new line, and we cannot type a "shif + enter" line break to force it.

Solution:

1. add an selectable option "automatic line break"
2. add a manual line break capability
