[Kupfer App Launcher] Crunchbang style theme

Hi everybody,

I am new to CrunchBang,  I was seeking around for a new distribution to settle based on Debian (or Ubuntu), Debian himself was okay, but I was also seeking for a Window Manager that I really liked and i found CrunchBang. I used to work on Ubuntu (Unity & Gnome2), Mint (Cinnamon & i3) and OpenSUSE (Gnome3) but i finaly found what I need : Crunchbang.

The only thing that I needed was a better App Launcher and I found Kupfer : nice, clean, and useful.
Also not so ugly (a la Gnome-Do), but the availlable themes were not so CrunchBang friendly, so I decided to make my own and to share it with you.

Preview : 

So the script is :

__kupfer_name__ = _("Crunch Theme")
__kupfer_sources__ = ()
__description__ = _("Use a Crunchbang Style theme")
__version__ = "1.0"
__author__ = "Jean-Philippe 'Orax' Roemer"

import os
import gtk

from kupfer import config
from kupfer import plugin_support

"""
Kupfer's UI can be themed by using the normal GtkRc style language
Theming can change colors and some pre-defined parameters, but
not the layout.

See also Documentation/GTKTheming.rst
      or https://github.com/engla/kupfer/blob/master/Documentation/GTKTheming.rst

please see http://live.gnome.org/GnomeArt/Tutorials/GtkThemes

View it online at Launchpad

Download and copy the script or create the file on the Kupfer Plugin directory :

/usr/share/kupfer/kupfer/plugin/

Feel free to tell me what can be changed and what do you think about this theme.

Cheers, orax 

PS : Sorry for my English

EDIT :
Kupfer is availlable on Debian Stable repo :

sudo apt-get install kupfer
