Possibility to send a request to friends or other streamers which are streaming together to merge their chat together while they are streaming together so viewers can chat to both streamers without having to have multiple chats/streams open.
Merging chat can also be used in another way.
PSVR allows chat to be broadcast to the VR headset. But only if broadcasting from the PlayStation.
However if you use a capture card and use obs from a pc you lose this ability.
In theory if you had a second channel with the PlayStation broadcasting, the merged chat could also broadcast to the VR headset.
This would be useful for psvr. You could use your main channel and obs for your actual stream and a secondary channel to put your chat into the VR headset. If anyone knows how to show psvr headset chat while streaming through a capture card please let me know.
Would make community interaction a lot better.
nvm Found same idea after posting. https://twitch.uservoice.com/forums/297558-general/suggestions/18959899-merge-chat
Make a command that will allow two streamers to combine chat for the current stream. This would allow the community to spread more easily when streamers team up. I expect a invite system would need for this.
Official support for Multitwitch or something like Picarto's multi-streaming (with one merged chat for the whole set of streams) would be awesome.
