One problem

Very good plugin, but one major problem. We certainly want posts to not be published unless they have a featured image. However, we have authors with status Contributor who write text for their posts and “Submit for Review” when they are done writing. An editor then reviews the post and adds an appropriate featured image. The problem is that the plugin doesn’t allow the contributor to “Submit for Review” unless the post has a featured image. Ideally, the plugin should allow this, and only invoke the featured image requirement at the time of publishing.
