Hi there, this has been covered everyone.
If you want this capability, you add it yourself in the Options areas.
Use Firebug or Chrome's native inspector and find the ID or class of an element you want to hide. In this case, the divs you want to hide are usually '.notice' or 'is-dismissable'. Add a name you want in the left hand text box, like "WordPress Notices", and add the class in the right hand text box, like '.notice'. Then hit update options. When the screen refreshes you'll see that option appear, and you can select it for the appropriate user. It will be hidden then.
