I highly recommend your yEd products, especially the diagram editor. I mainly use yEd for modeling BPMN diagrams. BPMN is an OMG standard for process design.
Recently, OMG published another standard in the area of Rule/ Decision Management: Decision Model and Notation (DMN) . For more information, please refer to .
If you could consider to add the DMN shapes to your product, this would be very much appreciated.
Thank you and all the best,
