Firstly, well done on this update, the plugin is brilliant. We had a play with the plugin a few months back but have been holding off using Edit Flow until this update as we were waiting for a few of the new features.
We do have one problem though; our users cannot set the status of a post (we have set up 5 custom statuses) unless they also have the publish_posts capability. The publish box just displays the usual 'Save Draft' and 'Submit for Review' buttons.
In our workflow, content can only be published by a senior editor, so we have removed the publish_posts capability from our contributors using the Members plugin.
Any help would be much appreciated.
