Many times when a chat is more quiet it can be hard for a streamer and other chat users to know when the last message, or a specific message, was attached. This can sometimes cause confusion especially if the streamer has added a delay and doesn't see a message for several minutes. I think that, like Facebook Messenger, you should be able to hover over a specific message/user to know exactly when it was posted relative to your own time zone. It's a very simple fix that I think a lot of users and streamers would appreciate.
