The current configuration page has a lot of empty space and on laptops, we lose half of the screen space instead of having a nice place to configure an extension
See: https://discuss.dev.twitch.tv/t/improve-extension-configuration-page-for-smaller-screens/20194/3

With the new design of the dashboard, Twitch introduced a new layout for the extension page.

It would be logical and great to have the configuration popup aligned to this design so we can have more space on the configuration page

game_id would allow an Extension developer to make further API requests for a game with the required ID.

Please allow the audio of a stream to run in background to allow for multitasking as the expected running time of a stream is several hours and if someone is on their phone it causes them regular interruption. Also, the screen at times is frozen when returning back on an app

like on ur channel u can desighn ur pic like put color on the outside and attach a pic to it and other stuff.

Currently, I find the docs hard to get through, although most documentation is there. It would be nice if you can go to the part of the docs that you might need, at the moment you are having a choice. For example when choosing what type of extension you want, that it will have a link to that specific documentation. Let's say you have chosen Panel, you then get a link to a/some of the example repositories for a Panel, the test channel, and a link to the documentation for creating a Panel.

Now it is not possible to get the number of streams in a certain section without sending a large number of requests to the API.

Adding the commonly-used game title field to the Get Streams endpoint payload (similar to the addition of user name) will allow developers to make less calls for the data needed. In other words, Get Games would not need to be called for every game id to get one more field.

Allow for the creation of highlights using timestamps/stream markers

Would love an API endpoint for "recommended channels".

Looking for a metric that helps determine what percentage of viewers tried out the extension. A developer can track the viewer count on their own, but they cannot guarantee that the extension loaded for each user. A metric is desired to calculate that X% of users interacted with the extension, not just a raw value of unique interactions.

For example, the YouTube Data API has the "fields parameter" to accomplish this, an example being: items(userid,username,title)

Thanks!

Boxart used on a category's Giantbomb page should be automatically set as the boxart on Twitch.

Twitch documentation does not state how to handle opening a new window on a mobile extension.

The Twitch Developer Rig should support pubsub whispers. It current supports normal broadcasts, but not whispers to target a specific user's frontend.

When user IDs in the provided data payload do not exists, the endpoint returns a 500 error. Ideally this should return a more detailed error code with an error message related to user IDs.

Some developers may need to cycle their Extension's whitelist with a big number of accounts. There's already an option to mass add users to a whitelist. So it's only natural to complement it with a mass delete.
