I figured this would have been easily integrated to XD since scroll effects are in Muse.

Parallax Effect Please. Very Important. Axure can do that thing. We need a parallax effect. Its gonna be awesome.

Please allow us to show parallax in XD!

Just make empty space in top of layer, and the paralax content bottom it.

Put an artboard behind another artboard and set an elo event like a "mouse scroll" makes a scroll of artboard-1 to artboard-2 like a webpage vertical scroll.

You can see also here justinmind prototyping tool is doing that : https://www.justinmind.com/blog/5-steps-to-building-web-wireframes-with-parallax-scrolling/
In this moment, I have to look after an other prototyping toll, just because there is not a parallax effect while scrolling in AdobeXD. I hope this feature will coming soon in AdobeXD.

Sure. Parallax is a very important feature while scrolling. Could we have something like in the beginning of the long form "Russia left behind" A parallax effect while we scroll. http://www.nytimes.com/newsgraphics/2013/10/13/russia/

There's another request here for more advanced freeform animation during scrolling: https://adobexd.uservoice.com/forums/353007/suggestions/12927846-custom-scroll-behaviour. We could keep this one focused on parallax and leave the other one for the more advanced behavior...

What sort of other effects do you have in mind, beyond parallax scrolling?

(Note: I've edited the title to clarify that this is about scrolling -- please let us know if that's not what you meant).
