I want to download themes for ubuntu 14.04, but I was confused because in the folder /usr/share/themes there are 18 folder. And the only folder that contains gtk-2.0, gtk-3.0, metacity-1, unity, and one file 'index.theme' that can be used for theme.
So I had to have a theme with gtk-2.0, gtk-3.0, metacity-1, unity, and the file 'index.theme'?
