Add ability to snooze
Add ability to snooze messages (i.e schedule messages to come back to the top of your Inbox). Many modern clients support this and it is actually already part of Outlook for iOS. If added, this should be available to use as one of the swipe gestures.

I agree with this request. Confusingly this feature is called 'Schedule' in the iOS app which is causing many to think that this is the ability to delay the sending of an email - but actually it's the ability to 'snooze' the email to the 'Schedule' folder and for it to reappear at a certain time and date.
