Display result
It would be very nice to be able to display result from the interface. Because usually this is the first you want after running a 'dummy' workflow. For more advance use case I think it can be different.
I know it can be complex as any kind of data is expected. But using the string representation of object for example could be useful. So for large numpy array we would have only the beginning and the end. For 'usual type' as int, float... it would be nice And for user special type then if they want to have something useful they would 'only' have to instantiate the function.
