sorry for my english, it's not my native language It's very simple, in a Metro app, move your mouse on the top of the screen to show the title bar, then move your mouse quickly to the bottom of your screen, and BAM check out my video tutorial: youtube.com/watch?v=Bn3afJXShGc
Yeah, it's more tricky without the hand. In my opinion, M$ should make two buttons: minimize for minimizing apps and X button to completely close apps, just like in Explorer.
Hmm. What I'm currently doing is moving my mouse upwards until the titel bar appears. Then I move the mouse quickly downwards, until it can't go any further. Is this correct?
Apparently the taskbar shows up within a Modern/Metro app only when you have "Show Windows Store apps on the taskbar" enabled.
