I'll think about writing something like this in future 🙂
Right now, you can get an API call of a user's latest posts, so theoretically you could write a simple widget that makes a call to that route (for the admin user) and renders the latest posts using the same code as the other widgets. So for a very basic implementation, if you know your 1-3 admins/moderators, you can easily hack it together using existing code 🙂
