I'm talking about when apps pop up notifications on your screen right over whatever you are doing at the moment....I want to turn all of them off for a fixed time period....like from when I say no pop ups until when I say they are ok. Can this be done? I hate when they pop up when I'm giving a presentation or something. It will be something silly like the Magic Piano or Sing! with a new song. I don't want those coming up in the middle of what I'm going. The Magic Piano always seems to send out pop ups at 2pm...yeah, I can turn that one off, but I really would rather have the feature done the way I want it done. Thanks. BTW, these are called "Banners" in Notification center. I want to disable them all, for any app, before a presentation and them re-enable them afterwards.
