Send a message to a contact from within Monarch

I often send quick messages (e.g. “I’m on my way”, “How’s everything going?”) to key contacts. It’d be nice to be able to do this within Monarch. I am imagining a syntax that’s like “message <contact name> message goes here”. Personally I only need iMessage support but the flexibility of allowing WhatsApp and other options could be good. I would also like to be able to Superlink particular contacts, so I could message my wife by just using a single letter command prefix.
