singleMainWindow property

SpecificationBoolean? singleMainWindow
getter/setter pair

If true, the application has a single main window, and does not support having an additional one opened. This key is used to signal to the implementation to avoid offering a UI to launch another window of the app. This key is only a hint and support might not be present depending on the implementation. May be present on Type 1.
