Quick Access Toolbar Word 13

I live and breathe macros. I have a few dozen icons on my Quick Access toolbar all mapped to macros. They used to fit on one line in the Quick Access toolbar with room to spare on a 24 inch monitor. However, when we upgraded to Office 2013, these icons displayed excessive spacing between them, so the ones off to the right only display when I click a double arrow.

There does not appear to be an option to display the Quick Access toolbar on two lines, nor does there appear to be an option to adjust the size of the icons so I can make them all fit again.

Can someone please tell me where to go to make these adjustments?

Thanks
