When I take a screenshot, its thumbnail and a little editing menu next to it stay on-screen for a LONG time. I've looked, unsuccessfully, for a settings option to adjust this behavior. I want to take a screenshot and then have its thumbnail IMMEDIATELY go away! As it is now, I can swipe it away, or I can wait an eternity for it to disappear on its own, but I don't like either. Is there such a setting?
