Request for another show column, or two

Is there a version that would show the
date-time modified of drafts and published
and then allow sorting by that column.. in the Posts and Pages admin areas. As I curate editors contributions, I need to make some adjustments as Quick Edit. Also, some posts and pages will be updated by co-admins and I need to locate adjust those as well by draft date and publication date.
Thanks for your great work and professional approach.
