Hello,
This goes beyond the tool today, but there is a significant interest in the functional requirements in the forums and this connects to it.
I would be interesting in having the ability to produce Message Sequence Charts and State Diagrams. I would propose having a type, similar to Actor/Use Case/Requirement for Messages and States then within the Actors, Use Case and Requirements you can associate the messages and states. From there the diagrams would come. Its probably not in the next release but something to consider as the tools moves into the area of functional requirements.
