I just noticed Code Review's FAQ includes "Application UI" in the "If your question is about..." section. What exactly is meant by that?
User Experience is the site for UI/UX issues, though UX.SE is not a review site. How does Application UI fit in with the two site's scopes? Is Code Review for the code side of the UI? If that's the case I wouldn't consider that "Application UI" it's just UI code.
In addition, this site is about "sharing code"--I don't see how pure UI issues could possibly fall into that scope. If the issue is "how do I make this code work to create this UI" that's an SO question; UI code is never language agnostic.
I haven't seen any questioned migrated from Code review to UX.SE so I don't think people are confused as to which site is for what, but I don't think this site's FAQ is very clear on what is meant by Application UI being in-scope.
