[Feature Request]

In the custom field builder UI it would be GREAT to see the field ID name along with the field name like so: https://s3-us-west-1.amazonaws.com/imgcaps/Edit_Field_Group_Session_Data__Aurras__WordPress_2023-04-12_10-05-06.jpg

It's a nice to have because they are easy (for myself) to forget and it could be a thing you toggle on and off in screen options but I would ask to have it on by default.
