Selective Reading

Allows website visitors to deselect categories they don't want to see on your blog.

zugrina

Small plugin that allows you to exclude pages or posts from WordPress administration post/page listing. It also works with custom post types. Pages or posts can be excluded per user role.
One good example would be a login page with a shortcode for login form. You want to make sure that this page is not deleted by accident.

Tailored Easy Exclude

Small plugin that allows you to exclude pages or posts from WordPress administration post/page listing, and post/page can be excluded per user role.
