Ola,
No, Lars' changes don't automatically become available to ad_form.
I modified ad_form so that it could take advantage of Lars' latest modifications, and also backported his mods to 4.6.
I also modified ad_form so it'd take section attributes to form elements. These were really small changes, but they work nicely. I'll be providing the patches as soon as I finish the Changelog for 4.6.
