There’s a new feature called Focus that allows you to choose which people and apps you’d like to see notifications from at a given time.

When setting up a new Focus mode, Siri can scan your outgoing messages and calls and automatically suggest allowing notifications from the people you talk to most.

There’s a neat trick here too: communications from the people you approve can come from other apps, like Facebook Messenger, not just from iMessage or texts.

You’ll also have the option to set a kind of away message when you’re using a Focus mode that will let others know you’re temporarily unavailable when they send you an iMessage.

It behaves like a standard notification, lighting up your screen and playing a sound or vibrating, but with an important difference: it’s allowed to break through your focus mode settings and notify you even if they aren’t from an “approved” app.

The option to see time sensitive notifications can be turned on and off by the user, so if you really don’t want to see them, you don’t have to.

In theory though, they should be for truly time sensitive events, like a package being delivered or your credit card company making sure it was you who bought two round-trip tickets to Maui.

Apple lets developers decide which notifications deserve time sensitive designation, so it’s more or less on the honor system.
