I love the Surreal theme, but I dont like the way the icons are in the middle of the screen covering the background wallpaper.

Is it possible to change edit the theme ?

Nope can't edit someone else's theme...

IMHO, the icons being in the middle of the screen is one of the things that make this theme unique. That is the last thing I would mess with. If one wanted a bottom docking zen theme, I would think they would just go find one. There are a bazillion of them.
