How is Experience Design CC (Preview) v. 0.5 different from the old Adobe GoLive?
Is this a low cost, easy to use version of Dreamweaver - similar to the olf Gol Live product that I used to use? (which I loved BTW)
XD is a tool for designing and prototyping user interfaces. It does not let you handle html tags and web pages like GoLive. There are requests for us to add the ability to export HTML or to make it easy to convert to HTML, so you may want to go vote for these features:
As Ray said, this is a prototyping app. The best way of thinking of it is showing how the project works before it moves into production. From there you can export the assets and then use them to build and code the web page or app. The Preview and Sharing panels not only show how the projects works but can be used in the UX testing process. XD should never be regarded as a web design app. Totally different use in the workflow.
