Have the current "Latency to broadcaster" more visible.
Sometimes due to bad connection etc the delay falls far behind, and it would be neat with a delay indicator visible somewhere. Maybe next to the viewer count, or why not next to the "chat" button?
I know there is a counter in the video playback stats, but since the new player rolled out, it's huge, and you can't move it around anymore, and most people just care about that one stat.
There is also a lot of new users that are unaware of the delay, or confused about how long it takes for the streamer to receive the message.
