Here you go:

I think I changed all of 4 lines 🙂
The unique id addon is done. Is there somewhere I can put it online for other people who might need it?
Thanks. That’s actually the first thing I tried. The problem with those solutions is the “id” changes if you change the order. I want to link to a slide (my sub_field), even if I change the order.
I looked at the template for making an addon. It seems like making a unique id custom field would be very easy.
