For most window types, no close icon (or minimize or restore) is displayed.
However, when I open the table editor, I see the icons for this window on the right at the level of the menu. Minimize and resize have no effect. Closing works there.
I'm using SDI with the settings "Don't show Tabs", "No Use multi-row tabs" and "Close button on tabs". Windows are usually maximized.
