Minimised sounds most obvious to me too.
A little known feature of Task Manager I stumbled over last week is "Tiny Footprint" mode. If you run Task Manager via the usual three finger salute and double click the bar where the tabs are it displays processes only; all the tabs, menu options etc disappear. To get them back you double click on the border. Took me ages to figure out where the rest of the display had gone and how to get it back, and I struggle to imagine a real use for such a feature.
