If we open a window using the WindowService and a custom component for the window content, there seems to be no easy way to disable the "minimize" action.
Example (pseudo code):
this.windowService.open({
                title: 'Execution Details',
                content: MyDetailsWindowComponent,
                width: 800,
                height: 600,
                minimizable: false, // < suggested feature
                maximizable: false  // < suggested feature
            });
Szenario: Esp. minify makes no sense in many situations (while we still don't want a "dialog like behavior" with backdrop and modal).
