Not having a layer management tool in Adobe Experience Design looks like a very deliberate decision from Adobe. I wonder why Adobe thinks that not having layers makes the app better and I wonder when Adobe will give up.
I've been using it for professional work since it launched. Never needed layers. Never.
Also, keep in mind that it is PREVIEW software. It is not a V1 release yet. They give it to people to get feedback and iterate. They have monthly releases.
If you want to request features you should post to their user feedback forums. They are quite active in addressing requests/bugs.
This ^ . Interface Design can essentially work without layers but people coming from the long adobe history need every tool to be photoshop in the end .
Accepting XD as a preview software and giving feedback is the best thing one should do right now .
You're probably right, interface design can work without layers, but I do think there is still a benefit to seeing and interacting with layers (hidden, locked, and grouped layers in particular).
There was a discussion about the implementation before the public preview. Their variations on the implementation were interesting and I can in some regards see the argument for not having them. I'm not sure on the specifics of the NDA as it's been a while, but it's not an oversight. I think it's one of those things where veteran users will miss it, but new designers that haven't formed a workflow around layers won't care.
I will say that some of the proposed concepts were very interesting.
