Anything else we need to know

"The Multi-Screen Window Placement API allows you to place windows on any display connected to your machine, store that placement, and make a window full-screen on any display. With this API, a presentation app can show slides on one screen and speaker notes on another. An art or music creation app can place palettes on a second screen. And a restaurant can show a touchscreen menu on a kiosk and a separate window for employees."
