The List Views window is displayed within the content pane area and is designed to display views used within a specific list.
The List Views window can be accessed by right-clicking on a list and selecting Objects followed by Show List Views.
Similar to content, users will be able to select one or more of these objects and copy them from one place to another.
To expose hidden lists (e.g. the Master Page Gallery) in the Navigator Pane, right click on the Lists node and choose the Hidden Lists option. After this is enabled, you will see the hidden lists for this location.
