Good to see I'm not the only one who wants this. I'm trying to make it look like the example in the attached image. I know which files to edit and so far I do have the attributes showing up on the page, and I bypass the more info to show the Add button when options are enabled for this page.
Currently It is working too good

its replicating the last option_name, option_menu for items that follow that don't actually have options. So I'm struggling through that for the moment because the attribs are really spread across the map with when and how they load so there is much to follow through. But I'm confident I can get it working (with hope).
