Voice messages

One thing that I see as lacking in all modern team chats, is the ability to speak and leave voice messages.

For project manager on the fly, writing or voice message can be a difference of a lot of time.

Productivity just jumps. 

Hence the reason why a lot of companies I know choose to use WhatsApp for voice messages.

If space would include this, I think it would be super awesome.

Btw. I like how you integrated chat into git repos, wonderful.
