I run a site with about 30 authors and 3 editors. Authors submit posts for review, and editors schedule or publish them. It would be useful to have another post status of "Editing" between Pending Review and Scheduled/Published. I realize there's a warning when someone else is editing a post, and that's probably significant enough, but I'd like to explore adding a new status level.
So, current post progression:
Draft --> Pending Review --> Scheduled/Published
Desired post progression:
Draft --> Pending Review --> Under Review --> Scheduled/Published
