How about adding a chat feature to the session?

[ByeongUkChoi]

What if we introduce a chat function that allows users currently in the session to chat with each other? The chat messages would not be stored and would disappear once you leave the session.

Hi @ByeongUkChoi! We discussed this a couple times. We temporarily halted working on more collaborative features because the best way to run Livebook right now is on your own machine, which defeats the benefits of said features. Perhaps they will make more sense for deployed apps, but we are waiting to see how they are being adopted before moving forward. :)
