It would be a nice feature to have some way to further customize–either through dashboard options or filters–the select drop-down (e.g., what user properties show up, and in what sort order).
For example, for a site I am working on I would have liked (especially on the front-end) to simply show wp_users.display_name (no login), sorted alphabetically (rather than by id).
I could also imagine a use case for wanting them sorted by wp_users.user_registered, etc.
Hi @gato-gordo,
Thanks for the feature request.
For the frontend values, you can use array sorting functions such as asort() to fix this on your template.

This function will sort the array, maintaining the index associations.
