For example: you go to one of your followed creator's channels to see if they're live; and as it would turn out, they're not live yet, but are hosting another creators' channel.

I am suggesting that instead of having to go to the other creator's channel to interact with their chat while you wait for your main channel to go live, that instead you just click a toggle that will show your message in their chat and vise versa; to eliminate the need to switch channels or open another tab entirely to engage with another chat while you wait for your streamer to go live.
