Sub Process Expansion

[simon.blackwell]

I'd like to see the option to dynamically expand/display subprocess detail on the same screen as the process that calls it. The Sub-Process bubble would then contain all its details to be viewed in the context of the parent process. This sometimes helps business people to get a better anchor on things. The Activity Diagram example from the on-line UML help illustrates my point except it has to be drawn statically.
