Fwiw. Hi Brink. According to Microsoft, the whole of the new taskbar is now merged into the quick launch. There is no need for a hack. Works for me!
Quote from the Microsoft Engineers:
"If one increases the size of Quick Launch, one must then determine what to do with the taskband. As previously discussed, we observed that under many scenarios of single-instance programs, launching and switching were equivalent. Hence, we decided to standardize this behavior and have program launchers turn into window switchers when they are launched. Effectively, we unified Quick Launch and the taskband. While some other operating systems have similar concepts, one difference with our approach is that our default experience always optimizes for a single representation on the taskbar. This means that regardless of a window’s state (e.g. minimized, maximized or restored) there are no new or duplicate buttons created. Also, the default taskbar doesn’t allow destinations to be pinned to the top-level which prevents duplication of a pinned file and a running window with that same file open. When we say there is “one button to rule them all” we’re serious. This approach to a single, unified button keeps the taskbar uncluttered and gives the person a single place to find what she’s looking for."
