Slack introduces threaded messaging

If the only thing that ever comes of this is containing GIF reactions to the original message's thread this is the best, most productivity-boosting slack update ever.

Very nice (and major) Slack update! The hardest part about this must have been the UX challenges to keep things simple while still adding the thread functionality and not compromising on the overall Slack appeal. Well done team.<p>Any Chatlio customers out there, we are interested in hearing how you might like this new functionality to used in Chatlio. (see sig for contact info)
