Need help changing gnome 3.4 icon size in dash
 

Hello,

I'm running gnome 3.4 and I like it very much. But the icons in the dash are very tiny, they are crammed in two lines at the top of the screen. I would like to increase the size of the icons. I searched the internet over and over again and found only one releted post, a tutorial: http://www.youtube.com/watch?v=oLrhLj11dPw
I went through the tutorial but the changes I implemented have no impact at all.

I would like to ask anyone who is more experienced in fine-tuning gnome 3.4 to help me with this minor adjustment.

I'm running Archlinux and I've already posted this question on the arch forum but received no reply.

Thanks,
