I'd like to be able to add some additional filtering to the Admin -> Users page (/wp-admin/users.php). Specifically, I'd like to add the option to filter by registration date or date range.
I've seen this plugin which comes close, but it doesn't utilize the existing users page, it hits a separate page which isn't desirable:
Is anyone aware of an existing plugin that extends the existing users page? If not, I'm perfectly capable of writing a plugin that'll filter users in this way, but I'm not finding a way to extend the behavior of the existing user page. Any ideas?
