I am project lead on the Eclipse Requirements Modeling Framework (RMF), which also contains a tool called ProR for requirements engineering (http://eclipse.org/rmf). In two weeks, we’ll start a sprint to improve the GUI. We welcome feedback, so that we can prioritize properly before starting the sprint. More details can be found here:
