[Plugin: Page Security by Contexture] No security filtering in the admin background

This plugin is perfect. But I find it doesn’t filter post and custome post types in the admin background. For example, I create a post with security access only to some users, but all users with more than author power can see all the post lists including the security limited post in the background. Sometimes the post has important information in the title, I don’t want others to see even the title, but I can’t deny them in the background.
I hope the plugin can filter all the posts and post types with permission in the background as forground. It will be perfect.
Is it possible to add such feature?
