I'm not sure if this is a feature but it's something I'd be interested in. I'd like to be able to snooze certain notifications so that they come up at a later specified time. Maybe just add it under the notification itself. "Snooze for "x" minutes". This would help prevent some clutter that doesn't need to be handled immediately like if I'm at work and a Twitter notification pops up I can dismiss it for a few hours til I get home. I feel like its better than leaving it as a notification cluttering the notification panel. Sometimes I dismiss things thinking I'll eventually get back to it but then don't remember.
This already exists..has existed for years. Expand the notification, there is now a bell on the bottom right and tap that. You will see snooze options so the notification will disappear and reappear in a specified time
