XF 1.2 Node lists

I unchecked the mark to make the sub-forums display below the main forum, but is there a way to make it into two categories? Rather than 3?

Or maybe a way to move the three columns over a little bit to the left? I feel like they are too spread out. I think it looks ugly being displayed under the last post. Looks a little clustered. If anyone can help out, I'd appreciate it.
