Is there a way to multitask in the "multitask" screen? I can't find any way to close out pages or save them. It seems to me its more like "snapshots" of the last few instances of what was done on the phone because the home screen often shows up here and pages or "cards" get replaced by recent actions. I often forget this "multitasking" feature is even here, because it's quicker (and basically the same thing) to just hit the back button. Thanks in advance if I'm just missing something because I would like to utilize this feature more.
