Enable pinning in secondary Taskbars in windows 8
In Windows 8, there is a multi-monitor taskbar support and it is possible to select the option to "Show taskbar buttons on:" "Taskbar where window is open".
However, choosing this option doesn't offer you the ability to pin the program to secondary taskbars. I don't know if it's possible but please consider adding this feature. It'll FIX Windows 8's multi-monitor.
As it is, the only way to do this is a heavy third-party app

I want to give this all my votes. I wish I knew Win32/Shell well enough.
