Mastery Button Sizes

Just curious if anyone could tell me where I would change the size of the mastery selection buttons so an added mastery fits with the rest.

I just want to make the selection boxes skinnier so all nine masteries fit in the one row but am not sure where to change this

EDIT:
I figured it out. I just had to edit the tex files for the buttons to be smaller. A little resize in gimp later and all is well

I’m a noob having a similar issue. I just need to get my 9th class on the window to look like your picture.

Can you give me a rundown on how you got your button on the window?
