The Adobe User Voice website https://adobexd.uservoice.com is where Adobe accepts new features requests. If this feature has already been requested, you can upvote it to add your voice. Otherwise you can create a new feature request.
Thanks for the link. Certainly would be nice to have all of the posting boards together in one easy place.
Adobe is using User Voice for feature requests and bug reports (so people can upvote and track the development process of Adobe's apps). These forums are for discussions and help. I agree it's a bit confusing for people at first, and it would be nice if the forums mentioned the User Voice site. But now you know!
The links are available on the Overview page, but I agree that not everyone lands up on that page. I will check with my colleagues to see if there is any other place where we can include these links.
