Automatic Diagram Layout for Sequence Diagrams
Finally, automatic diagram layout is available for Sequence diagrams.
This will shorten Lifelines, Execution Specifications and messages to reduce unnecessary spaces to layout the diagram in the best representation possible.
Now you can only focus on the contents without worrying about the layout.

Get target model without a scroll
Now you can see the name of models located outside of the editor.
You no longer have to scroll all the way to the target end to see what it is
Also, a new [Move to related element] menu lets you jump to the target end directly.
This will help you work on the diagram in the best-sized view always.
