Seeing Red Documentation
Screenshots are available on the plugin page on wordpress.org.
What is the idea behind this plugin?
I work with a lot of people who are new to WordPress, and they are just never aware of the Screen Options tab. It's one of those things that you need only rarely, that power WP users are well aware of, and that is a complete mystery to noobs.
Is it possible to hide one or both of the tabs?
Not with this release, but I will add that if there is interest.
It is possible to customize the plugin's appearance using a child theme. (I'm not sure if WordPress 4.7's new custom css feature will affect the admin pages. I need to investigate this.) (Add instructions here.)
