We are currently developing the visual and interaction design for the S-RAMP UI.  The first draft of the Interaction Design is available here: https://docs.jboss.org/author/display/SRAMPUI/S-RAMP+Interaction+Design+Spec

There will be more changes and refinements coming in the near future, but we'd just like to share where we're at now.  Feedback is appreciated. 

Related scenarios are available here: https://community.jboss.org/wiki/S-RAMPUserScenarios.  Note that not all scenarios will be covered in the first phase of the project.
