Hello Joerg,

this sounds like the most innovate suggestion made since a while. From my
first impression, we should do this. It comes in the right moment, because
I want to do the last mayor improvements for the first release candidate of
the beta branch.

If you have further suggestions that would have an impact for the API please
hurry, because it's a problem to change the API once the beta branch has
been started.

But I have 2 questions:

1.) Should we use the same pattern for the parameters and the configurations
object?

2.) We have the tree of plugins. How does the registry know, which
controller is needed for the current plugin? Example: The program flow is
in the result browser and the result browsers controller is requested.
