Message Drafts/Scheduled Sending

I'd appreciate the option to save a typed message as a draft. Along with the message content the guild&channel/dm you were typing it in should be stored. Preferably you'd be able to access your drafts from any platform and you'd be able to access all your drafts at any time, with the relevant ones stored at the top. What would be a dream is to also set messages to send at a specified time, though maybe only 1 or 2 allowed per server/dm to be set at a time. Both of these should support attachments as well. While it is not the most needed feature, it'd be a big help to have at times.
