In XFce4, when I launch applications, I don't want them to appear above the windows I am currently using, or to show alert windows above my current work. Rather, I'd like the windows to load in the background and to not steal focus. The exception would be an alert window or dialog belonging to the application I'm using, e.g. if I am currently using LibreOffice Calc, and it gives me a pop-up to tell me an error, that window can be brought to focus.
Is there any way to prevent windows from stealing focus in Xfce4?
