Hello everyone, I just installed Ubuntu Gnome 13.04 and I am having trouble customizing it. I installed shell themes, but they don't show up in the Gnome Tweak tool. And, the menu bar won't change color with my new wallpaper. For example: I want it to look similar to this [http://img.netupd8.com/my-humanity-icons.png] but don't I know how to change any of the settings to make Ubuntu look better. this is getting a bit frustrating!! Please help! ](*,)
