I have installed a jBPM and looked it roughly, found that the jbpm workbench looks more beautiful, especially there is a DataSet panels, almost do the same work of what Our designer do, as [1], current, RDBMS. excel/csv file, Elastic Search be support to import and mapping in web UI.

Also the UI more moderner than our Designer, I would attach some screenshot
