Coordinate User Field
When this is added to a form it captures the GPS coordinates when one of those forms is created via the mobile App.
Renaming user fields to link/unlink from the Form
When renaming a user field you now have the option to link the new code with the form or to unlink the new code from the form.
If you choose to unlink the user field from the form you can recreate a new user field with the old code and it will automatically link it with the form.
