This is good. It worked ….
But I noticed that any notices that show up…. during that time of access, can be viewed by the user …
In terms of iThemes security issues …. when it shows up …and the user with restricted access clicks on that … it goes to the page of the iThemes security settings page, where the settings can be changed and saved. I think this could be a security hole in user role editor. Kindly check it.

Also, is there a possibility to restrict access to only a single slider on the revolution slider, than the entire lists of sliders? That would help protect changes in various sliders available.
