Google have just added “manual actions” to the navigation in webmaster tools.
I can’t tell yet what it will show other than warning and maybe the awaited examples of problems e.g. bad link examples or problematic pages/structure
It really looks like google is opening up a lot more to webmaster which I think is great news.
