The bflow* Toolbox is a modeling tool for the business process modeling language Event Driven Process Chains (EPCs). In this paper, we describe three innovative features of the modeling tool: First, the modeler gets continuously feedback about possible modeling problems. Second, there is an option to construct a large part of a model with input from the keyboard only, i.e. without ever touching the mouse. And third, new features can be added to the tool very easily - without the need to be familiar with Eclipse development.
