While it's merely a glorified "Do not disturb" option in the app, it might help remind you to step away from Facebook. The social network introduced a new Quiet Mode feature that lets you set limits on how much time you spend on the app. It mutes your push notifications, too. If you try to open Facebook while it's in Quiet Mode, you'll be reminded that you wanted to set this time aside from using the app. Social media might be our only way of staying connected to the world, but Facebook acknowledges we need to set boundaries so we can establish new routines at home.
Facebook also mentioned in its press release that they have "added shortcuts to Notification Settings and News Feed Preferences, so you can make the most of your time on Facebook by controlling the type of posts you see in your News Feed as well as the updates you receive."
