It happens that special privileges have to be applied on workflow elements, dashboards or views. Unless we work on a system with different test users, it is quite difficult to check whether a certain user really has access to right artifacts or not. 
Sometimes i also get support tickets from customers telling they would see or not see artifacts. 
As an administrator oder system administrator it would be great, that we can simulate a user. 
Within the simulation mode, we would be able to see what "user A" does. 
Of course we should not be allowed to execute any action on behalf of this user.
