This is a great tip. I also found this out a few weeks ago, and I think it’ll help some people.
I just wish this wasn’t such a hidden feature. There’s no visual indication that users can do this, so I keep forgetting to do this. I’m trained to swipe to dismiss now.
Also, sometimes I want to just turn off some notifications, not all of them. You can tap the gear icon, but some app settings are still pretty confusing. For example, the Facebook Android app has two different places where you can adjust notifications: App Settings and Account Settings. It just doesn’t make sense to me.
