I think a great feature would be to have a general chat for an entire workspace so a team could communicate. Rather than having to click into each space or list and look at the chat view's created there, it could all be in one place like slack or Google chat.

However, every space or list specific chat in the general chat, could be synced to an individual space's or lists' chat view as well.

So whether you are in the general main chat area or you are looking at the chat from within a specific space or list, the conversations will be synced.
