I'm a developer working on a browser extension that's a combination of things for the Twitch streaming platform. It's free and open source. Here's a description of the features.

For a Twitch user, you can connect the accounts by clicking on the StreamBlend icon in the browser toolbar, and then clicking on the gear icon.

When you have multiple accounts, you can now see all your streams merged in the Twitch sidebar.

The features on my website are very simple and easy to use. You can see them all here.
