The option to mute a conversation from the notification without having to open the app, go into the conversation, go into the conversation settings, and click the button would be very helpful, particularly when getting bombarded by a group message when you need to keep notifications on for other groups. Facebook Messenger offers an option like this in their notifications that is very helpful. Also if possible like Facebook Messenger, it would be helpful to have the option to select various times to mute for, say like 1 hour, 8 hours, 12 hours, 1 day, or until turned off.
