A Pane Option Menu is a Menu that holds various Actions that typically pertain specifically to a given Pane (Tab) or are closely related to a concept that a Pane provides access to.
A Pane's Option Menu can be accessed by clicking on the pane_options_button, in the corner of the Pane (Tab) Group closest to the Viewport when that Pane is the selected (or “active”) one in that Pane Group.
