Just some feedback for a future version. When I use the “restrict post view” function for the categories I don’t want the user profile to view on the front end and backend of the site, the category names still appear in the back end post edit screen when filtering all posts by category. You cant actually read or see the posts for the restricted categories – just all the category titles in the filter’s drop down. It would be good that these are hidden from the drop down also. I hope the plugins don’t clash, but by using your plugin combined with a plugin called “Restrict Categories” – it fixes the issue as a workaround 🙂
