i've been working on os x app in xcode. option perplexes me "presentation", 2 options "single" , "multiple" attribute do?

enter image description here

so, "obvious" once used it.

to see in action, add create storyboard view controller in it. place button on view, , additional window controller. create segue between button , window controller "show" window controller.

click on window controller , toggle between 2 presentation options. when run it, find 1 case create multiple instances of window, while other create single instance of window.
