Indicate which pages are newly created in Page Tree

Summary

It's now possible to create child pages right within the Page Tree sidebar:

When the page is published, you are automatically land on the new page, so it's highlighted in blue as the current page.

However, users want a way to tell which pages were recently created.

Suggestion

Allow for the users to set a specific timeframe of what's considered new, and then mark those pages in the page tree as new for that period of time.
