One of the cool things Activiti has since its beginnings is the workflow diagram. This diagram is created during the workflow definition, typically using Eclipse's Activiti plugin. During a workflow's lifetime that diagram gets updated indicating the state of the workflow by highlighting the current task.
With its lastest release of the Activiti Designer, Activiti has moved more than a step forward in workflow definition and development. This tool was first announced a while ago (in the Alfresco DevCon 2013 celebrated in Berlin) and has been a very demanded one from developers and business people.
This tool allows the easy creation of Activiti workflows including deployment to an existing Alfresco repository. Apart from the process definitions, this tool can create the corresponding workflow model and form definitions and deploy them.
