    mainWindow: Do not call show_all() from _init()
    
    The expected behavior of widgets in GTK+ is to show all internal
    children that should be visible when the widget is shown, but
    leave its own visibility to the parent (or the code that created
    the widgets). Not following that pattern is confusing for any
    widget, but much worse for toplevel windows where the widget's
    visibility directly corresponds to the visibility on screen.
