I get issues every now and then with a customer that gets into the titles search section, often times by accident, and they don't know how to get out of it. I'll hear them asking "how do I get out of this screen" and more often then not it's because they simply didn't notice the tiny X in the far top right.
Of course, it's just like everything we're used to on a PC, the X being in the top right to close out, but when they're in VR I guess it's not expected now that a UI should be similar to Windows. Also, a lot of our customers are very young and are probably more familiar with UIs that don't have the X in the top tight anymore since they're more familiar with smart phones that just have you swiping to close things, not an X.
