Abstract: The present disclosure pertains to user interface controllers and overlays. A portion of the user interface may be covered by an overlay, which may be generated for certain states of the user interface. A user input may set a first selection of control elements of an interface controller in a user interface. In the user interface, particular selections of the control elements may be configured to cause corresponding sets of potential interface elements to be displayed in a portion of the user interface. It may be determined that the first selection of the control elements is configured to cause none of the potential interface elements to be displayed in the portion of the user interface. The overlay may be generated based on a display-level of the interface controller in the user interface, where the overlay covers portions of the user interface while not covering the interface controller.
