When swiping away a notification for a new incoming txt that you cannot read/respond to right now, instead of simply disappearing, an option to "remind you later?" of the txt comes up, similar to "snoozing" an alarm or setting an alarm for a time. Options could be "remind me in 30 mins, 1 hour, 3 hours" etc and can be customised or "remind me at 5pm" and the time could be set to user preference
