When utilizing chat as a team, transitioning back and forth between conversations is somewhat of a cumbersome problem—you can only have the context of one chat at a time. It would great to see either (or both) of the following:
When chat is full-screened
Use the sidebar to prioritize DMs and chat channels over everything else (or better yet, don’t show anything else at all)
When chat is not full-screened
Have the ability for having multiple chat windows open so you can maintain the context of at least 2-3 chats
Have the option for a persistent chat on the right-hand column of the site
