We've decided to handle all product SEO as our vendors don't have a clue what that is. So, I'm trying to hide the "SEO" tab in the product admin (i.e. products.update and products.add) for vendors, but keep visible for admin. I managed to hide all of the content of the tab (by modifying /design/backend/templates/views/products/update.tpl), but not hide the tab itself.
Can someone please point me in the right direction?
