Your entire dev site has no sidebar on mobile so you can’t get to most subpages without digging. Can these be added to a hamburger menu at small resolutions please?

This is really very cool. Thank you for taking the time to create such awesome documentation. I am a front end dev for a well know travel website and I appreciate the effort that goes into making this.

https://dev.twitch.tv/support has no links to the dev Issues repository for bugs, or the uservoice for Feature Requests

This documentation isn't clear enough, it implies that the ID attribute should be set to the channel name, but for whatever reason it has to be set to 'chat_embed' and then the channel name goes in the SRC URL, replacing the 'hebo' text. There's no description of how the 'src' attribute should be presented so this isn't immediately clear.

"WWW-Authenticate header" vs "WWW-Authenticate header"

EDIT: Another bug here https://dev.twitch.tv/docs/api/webhooks-reference#subscribe-tounsubscribe-from-events

"...if the parameters supplied are you receive an immediate..."

Reads like there should be something after "are".

Getting the list of a channel's editors for e.g. importing, and verifying editor status is something that is missing from Helix.

Kraken had this in /kraken/channels/<channel ID>/editors and it was very useful.

The ability to verify your Twitch editor status is necessary to properly interact with Twitch's editor features.
