Yes, I agree. We definitely need a progess bar for WMX. Our client is the National Mapping Agency for Malaysia who recently switched to ArcGIS products They have started to use Workflow Manager with many workflows. The first comment is how do I know WMX is running my geoprocessing tools in the model and what is the progress so far? This has been their top request. I hope Esri will consider adding this functionality as soon as possible.
