I do not know if there's an add-on already, but it would be nice while at a crafting station that when you hover your mouse pointer over the item (e.g. Chest Heavy), a cut-away or enlarged view of the item appears in a sub-window that slowly rotates that item. That way you get a decent look at your item without having to test the look at an outfit station.
Hopefully I explained that to where it makes sense.
Thanks
