In user permissions i let users with editor role "Access the content overview page". And this page showing them all added content. I can make a view with this user added content, but i want to achieve this with "Find content" page. How can i achieve that? I want users to show only the content they added.
I don't believe that's possible with the Find Content page. You may have to resort to making a View to accomplish the task. I've created several views for the same purpose, and actually prefer it as I can create my own admin links (edit, delete, view, publish, etc.) customized to what my goal for the page is.
