I Really love the Clone field and how it works when using the Group Fields options. This makes naming fields so much cleaner as I no longer need to give prefixes for so many names. For instance I have a section on all my pages called “hero” it has lots of fields in it like Hero Title, Hero Subtitle, Hero Color etc.
I only prefix these just in case there are other fields on the page that are basically the same thing.
I guess a better way to think about it would be a repeater field with min and max of 1 set of sub fields
as with other feature request, I’m going to refer you here https://support.advancedcustomfields.com/new-ticket/. The developer does not really read these forums unless his attention is called to a specific topic. While he is still interested in feature requests he’s too busy to look at every one himself and the normal support team keeps him updated on these.
