The Elevator Pitch

Everything happening in the Purple Frame will also happen on your Stream Overlay. Invite anyone you want as an Editor, given they have a Twitch account, using a nifty invite link or by adding them directly.

Just be warned
Anything they add will be shown on your Stream, so maybe not literally "anyone".

Quickly have someone else add texts and images on Stream without having to tab out or interrupting whatever you are doing. Show funny memes, contextual information to enhance the stream expierience or just shitpost away.

The World is yours, or in this case the Overlay.

Sizing and several manipulation options are also available for each Object on the screen by selecting them and using the Sidebar.
Spin images, resize them, make them blurry, change text fonts, the text outline color and so on, you get the idea...

It's nothing groundbreakingly new, but it is what it is.
Feel free to reach out if you are interested in testing it on your Stream, worst case I say no. :)
