Hi Adobe,

See my screen recording to see what I'm asking for.

I've needed this feature for multiple projects. I'm an expert user.

Thanks!

Hey - just so you know, this is a user to user forum. You'd have better luck letting Adobe know of your request via: https://www.adobe.com/products/wishform.html

Can you show me an example?   My goal is to animate text downward, scrolling, and have the text look like it fades out as it reaches the bottom of the screen.
