How can I easily display *all* currently running Metro apps in Windows 8?

http://superuser.com – What is the best way to list all currently running Metro apps in Windows 8, included those which have been minimized by dragging them down to the bottom of the screen? Initially, I assumed the "Switcher" bar on the left hand side provided a convenient way to see all Metro apps; however, it now seems that any apps that are minimised do not appear anywhere except the Task Manager. In the Metro interface, running apps have the same icon as ones that are not running (correct me if I'm wrong). Add to that the fact that minimized apps do not show up in the Switcher bar, or even when you alt + Ta (HowTos)
