Missing editor role
On the terms page (https://safety.twitch.tv/s/article/Twitch-Terms?language=en_US).
Since editors are a role with elevated permissions explaining this to potential new creators would be ideal.

Thanks so much for reaching out with this feedback!
We have added Editor: Channel editors are appointed by the channel owner and have access to the channel’s dashboard. They may help manage the channel in a number of ways including editing stream info, running ad breaks, editing video information, uploading videos, starting reruns, downloading past streams, managing clips, and setting clipping permissions.
Please let us know if there are any more terms you would like to see added to the Safety Center.
