Creating a "Related pages" view which also excludes the current node
If you use Views content panes and Panelizer, then:


Set up the view as a content pane with argument input for the Node ID (Nid). Then, set up a contextual filter for Content: Nid and check the "Exclude" box.
In Panelizer, add the view pane and pass the current node ID to the content pane as a the Nid argument.
