The initial evaluation of EasyComposer has provided much useful feedback to the tool developers. Several usability issues were discovered. For instance, component settings have to be refined, connections between components to be improved, and save and load functions to be added.  Several issues have been clarified based on the feedback provided by the evaluation workshop participants. The workshop as a whole gave an excellent first real test of the tool. We plan further end-user tests of EasyComposer in the near future.
