Layout change for displaying Users

Hello,

need a little assistance... for our site I like to change the display layout for Users to the same way Pages will be displayed in ES.
I like to have a view for Users like I get if I add the menu item "Pages". This view should also be addable as menu item and should be associated to single user profile(s).
So i should have a to modify the view of the existing menu item "User" to have Users displayed like in menu item "Pages".
Could you give me a hint which files are necessary to be modified?

Thanks
Andreas
