As of the latest Release of Linchpin Enterprise News, there has been a change in the permissions for news in workflow spaces (and for good reasons, we won't roll that back ;) ).
Now any planned news is only visible for the author and - in case there is an approval workflow - the editors. But not for other authors in said space.
In many cases that's okay. But sometimes there's a group of authors who need to work together and see each other's news while those are not published yet.
For those cases, there could be a configuration option per space. Similar to defining the editors for approval workflows, you would be able to define a group of authors who can view and edit each other's news within the workflow space.
