Thank you for the patience with us on this. This has been one of the most popular ideas on UserVoice and we definitely heard your feedback.
Today we launched /announcement for mods and streamers. Announcements can be used in chat to highlight a message and are available in 4 different colors along with the channel accent color. Because this is only part of the ask of this idea we are setting this idea to partial release so the community can continue to leave feedback on this.

The new announcements are great! But a little enhancement that would go a long way would be if they could be "pinned" to the top of chat for 30 seconds or so (similar to how Youtube handles broadcaster messages) so that chat could always have a chance to see them. While announcements will be great in smaller chats, in fast-moving chats they may still go unnoticed, and doing something like that would go a long way to making them more effective at communicating important messages.
