Reply To: Duplicate fields on the backend

Hi,

Good trick on get_current_screen()!

Regarding the user language, the field ID (for user meta) is locale. However, the list of options you need to make by yourself.

The display name has the field ID display_name.

The "Sessions" button is just a simple button and you can do that with button field. However, to make sure it works like WordPress, you have to do the code to log out from everywhere by yourself.
