PublishPress Checklists Pro GPL Overview:
PublishPress Checklists allows you to control the quality of your WordPress content
When you use PublishPress Checklists, you can define tasks that authors must complete before content is published. Tasks can either be recommended or required. As writers complete each item, the red text automatically turns to green.
For example, you can make sure your posts have a minimum or a maximum number of words. Or you can ensure that all your posts have a featured image.
