This is a really simple idea, but I found myself looking for a feature like this multiple times now. The idea is to give streamers an option to link their collab streamer collogues twitch profiles, so the viewers have it easier to find their accounts. The way many streamers are doing it now is with bots (you type a specific command and get the link to the collab partners profiles) but I find that to be a bit confusing sometimes as the available commands are often not listed clearly and a unified way would be much simpler for the user. You could just put some links directly under the stream player where every profile is listed.
