Option to set Pinned Items Icons size (as more small has more space on taskbar)

This is about the only thing I find missing with 7+TT. It's not really an issue on my desktop, since I have a larger screen, but now that I'm using a laptop a lot, I wish I could make the pinned items smaller. They can be made smaller in Windows, but that of course shrinks the height of the taskbar, too, and then it won't show the date, which I like to have displayed. So it would be great if 7+TT could shrink them without doing that, so I could have more space for other programs on the taskbar, since currently the pinned items take up ~1/3 of it and the system tray icons take a little over 1/4, leaving ~40% of a 14" display to show everything else.
