If you have the permissions to "manage views", you are able to add/remove/reorganize the items in a view to customize that view as desired.
1. In the left pane under the Views header, locate the View you wish to edit.
2. Choose the Edit (pencil) icon from the Views home page, or if you're already in the view, choose More-> Edit View (this option is temporarily disabled for initial launch and will be enabled in a future release)
3. Modify the View components as desired following the steps in Creating and Cloning Views
