Thank you for your reply!
For my particular application, it would be useful if each item in a list had a unique number. Many elements look the same in the preview. For example, if you talk about it on the phone, it’s easy to say “number 17” as “the 17th entry”. The number does not have to be consecutive, just unique. The ID in the WordPress table wp_posts lends itself to this: If you get an entry from this table (“select * from wp_posts …”), you will automatically receive the ID. It would be nice if I could select this ID in the meta information. Or separately in another way like a separate function.
I know – nobody needs it except me :-)…
Sincerely
Ralph
