I think a user-profile option to disable automatic joining of a raid would be a useful feature. Some channels have various reasons or incentives to staying in offline chat and sometimes you can't catch the whole stream and can't opt-out of the raid.

if a channel host raids another channel it will switch your url which will delete chat history as well some channels have "This room is in 10 minutes followers-only mode." so some raiders can't raid

1 having the option of turning off raids for a certain channel your in so you don't get auto switched or turning it off completely for all raids because maybe you like switching to a different channel then join a raid.

When ending stream and raiding another streamer, let us suggest or adjust the volume for everyone joined in the raid. I'd love to be able to raid and set everyone's volume to like 10% on the stream we visit. If they are awake, they can adjust it back themselves. If they are asleep, they won't be disturbed. (Maybe don't let the volume adjust take effect if the viewer has the stream muted already).

Give an option to flag your twitch that you're ending soon and wish not to be the target of a raid. Often times I see streamers get raided close to when they would be ending and are put in a position to have to either a) stream longer than they wanted to or b) be overly apologetic out of guilt, especially if it was a sizable raid. I think it would make a nice feature for the creator dashboard quick actions.
