The creator dashboard available to broadcasters has a section with Streaming Tools that helps them identify what third-party tools can support them to achieve a high-quality stream.

The same experience should be available on the dev site so new developers can find which third-party tools they can leverage to build a top-notch Twitch integration.

Partners get a verified badge, it would be nice for published developers to get a badge too, maybe after a certain usage requirement of their extension, like how partners have to hit certain limits to become partner, maybe enough usages or page views of the extension will get a dev a badge.

Currently the management of extension SKU's is only done via the Developer Rig.

Since the rig is an optional, many people are developing / testing without using it & the fact that its a development environment, its a strange place to place/manage production SKU's. These would be better managed from the platform itself under the Monetization tab of each Extension.

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

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.

Allow developers to sign up for a specific time slot where they can rely on an extension reviewer to review the extension.

Game developers can currently upload only the boxart, but to upload the banner they have to reach out to Twitch to update. It would be nice to have this moved into the site to make it easier to manage.
