Phil asks, Phil gets. Yelp has an editor mode, which looks like this:
In editor mode, Yelp shows a revisioon banner along the top, as well as revision badges next to link boxes. It also shows editorial comments, though that’s not in this screenshot. Also notice the “Stub Page”. This comes from a file with the .page.stub extension, instead of the regular .page extension. This was an idea Phil had to help us stub out extension points in documents when we write them. Yelp only shows stub pages in editor mode, and it gives them a red background so you know they’re stubs:
And, by the way, this is no longer yelp-3-0. This is master.
