Again, I love the plugin... Here's another feature request.
I require authors to enter 1-5 tags, select only one category and require the author add a featured image.
It would be nice if there were a note in each of the meta boxes telling authors what is expected of them.
As a workaround, I have edited core WordPress files to include notes.
Featured image, located in wp-admin/includes/post.php
Tags and categories, located in wp-admin/includes/meta-boxes.php
