Since everyone has this by now, I may as well make it fully public.

2 Extra bars for Zaken patch.

How to install:
Download and extract the version you like(1 or 2 extra bars) and move the file Interface.xdat to your system folder.
About key bindings:
You currently can't bind keys to the bars. The numbers you see on the top left of each button don't correspond to any binding, they're decorative(I was too bored to find out how to remove the numbers). It's probably possible to associate bindings with the buttons but I can't be bothered and I'm not sure whether admins would like that anyway
Enjoy.

@Phoenix for giving us the first bar so I can make something similar for zaken patch.
