Word 2010 - we can't modify the ribbons that are the defaults - we would have t start from scratch and build completely new ribbons, and we can't make new toolbars or move them like in Office 2003.
We had more and more flexibility as OLE developed, but now MS is backtracking and making too many decisions for us, just like Apple does. If I wanted a company to make all my decisions for me I would have bought a MAC.
