Twitch staff here. A streamer mentioned they'd love if there would be an option to have whispers from their Mods to appear in their chat and be highlighted. The streamer mentioned they use pop-out chat and primarily uses the chat of engagement, and this would help them keep the flow of their stream without having to pause and click through the Whispers window to see specific messages.

In addition, maybe add an option for everyone to toggle having whispers mirrored to a chat if they are watching a stream with the @USERNAME and a notice it is a whisper. Just want trying to convey ways to make whispers more functional, noticeable and user-friendly.
