You will need to make the queuebutton width fixed (set in em or px, and not % as it is right now). And then modify the index.html file and play with the grid_x classes for each section. Fop2 is using the grid960 system, you can google for it and learn how it works, it is not that hard.. you can move the queue div to be a grid_16 at the very top, before the extensions div so it will fill the complete screen width. I do not remember the div names from memory, but it is pretty easy to grasp once you look at the index.html
Best regards,
