Is there any application to change the complete look of KDE like a theme in gnome? Without changing the colors, icons, styles, backgrounds, decorators and so forth individually but in one process instead?
Something like a theme manager?
I would like to create a complete KDE Desktop look & style and then share it with friends without setting up 8 sets of settings with all kinds of importing files and setups.
There is a KDE4 desktop theme manager in the advanced tab of the settings panel. But if you need to change things outside of that then you need to talk with the kde developers in order to make something more complete and cohesive. So far people on http://kde-look.org/ probably have the most advanced ideas on how to publish and deploy entire themes.
Anything they don't know, probably doesn't exist.
