improve lay-out of swimlane diagrams

Question

Feature request to improve the swimming lanes layout.

Enclose the total diagram in a frame so that the diagram lookes nicer and more conform the way visio would do.

Diagram title in a separate frame

Answer 1

I really like PlantUML, 

Could simming lanes layout support this structure? There are not only vertical swimming lanes, but also activity steps from horizontal view.

Thanks
