Extend options for list/detail display and sorting

I love the feature you introduced with #858! Thanks a lot. Now I do have an idea to extend this feature a bit:

* It would be great to add the creator in the list view and 
* to disable the workflow state for the list view and the display.
* Finally it would be great to have a different setting for the frontend and for the backend.

Might be you will introduce this with 0.7.1 ;-)
