Edited Zukitwo themes for Xfce with Black Crystal (Vista) Xfwm4 theme.
The package includes:
1. Zuki Xfce Dark V "Original" for version of GTK 3.16-3.18 (Debian Jessie and Ubuntu 16.04)
2. Zuki Xfce Dark V2 "Alternate" for version of GTK 3.10-3.18 (Debian Jessie, Ubuntu 16.04, Ubuntu 14.04, CENTOS7...) with edited GTK3 configuration from theme Greybird.
3. Zuki Xfce Dark V for version of GTK 3.19+ (Debian Stretch, Ubuntu 16.10+, Fedora 25, Arch Linux ...)
4. A few of my favorite backgrounds for dark panels.
