I found it. Go to the highest level of your project explorer. With the right mouse click – you are able to select “ Export Documentation” . It will be stored in html format. Open this format via google chrome and you will see the overview of all the microflows – parameters and domain model – attributes.
I think this isn’t possible out of the box. Maybe you could build something withe the MxModel Reflection. This should contain a lot of the information you’re looking for. Take a look to the App Store for the related Module.
