I have a couple of feature requests. First one is a small one but a small UI change each of my teammates ran into. It would be nice to be in the Inbox and not have to be "stuck" in a chat, meaning you have to be viewing any active chats when in that window. There have been many times when me and my co-workers clicked the Close button on the chat thinking it would just close the window.
Second, It would be nice to have an exact timestamp on the chat messages because anything over an hour just specifies the timestamp in hours or days which is not very helpful for reviewing chat times for certain purposes.
