Remain in islands
    This checkbox allows you to control how Sloop deals with "window islands." Window islands are windows that are smaller than the windows behind them or that would be obscured by a switch.
    If this box is checked, and the frontmost window would be obscured by a switch, Sloop will not switch out of the frontmost window. If this box is not checked, Sloop will treat all windows in the same way, regardless of whether they are islands.
    This preference can be convenient if a lot of your work involves small windows.
    Please note that this preference only applies if the frontmost window is an island. It will not prevent other windows from being obscured. So if the island is not in front, and you focus on the window behind the island, the island will still be obscured.
    Also note that this preference applies among applications as well as among windows within an application. So if the frontmost window would be obscured by focusing on another application, this preference will prevent Sloop from focusing on that application.
