desire adm setting for list count in adm view

Would be really nice if adm dashboard or general panel had setting where one could set item count of page list and post list when editing.

I edited post.php from 20 to 40. I have70+ pages in this site. It is really slow and inefficient to page thru pages to find the “page” I want to edit.

I tried to the same for post edit list page but couldn’t find where the number is set. Why so low at 15. Should be at least 30.

Anyway should be easy to implement a simple control to customize this. Hope this makes 2.8
