Engine should be able to render to multiple windows simultaneously. Features to implement:
Displaying two independent windows within the same application on two different screens (see similar feature added to ex. GRID Autosport - secondary monitor displays TV-like live recap of what is happening during the race. Other use cases are additional help info on second screen, independent map display etc)
Rendering extended to multiple displays at once - allows for increased FOV and more details shown. See how such situation is handled in ex. Battlefield 3.
