Ubuntu is just completely confusing atm. It's a beta, so I can expect that. Generally it works fine for me, except that the themes that works fine in Arch on the same version of GTK3/Unico doesn't seem to work the same way in Ubuntu. If I try to patch my Zukitwo theme to work somewhat better in the new Ubuntu I loose border-radius and some hover effects in the theme on Arch. Are the Ubuntu devs messing with GTK3 by adding their own patches or something? I can't make a universal gtk3 theme if that's the case. Expect an update on Zukitwo and Zukini for other distros around the time when Gnome 3.4 is released. But if Ubuntu stays the same I suppose I need to abandon support for Ubuntu.

_{Btw, Unity still is pretty bad and not something that I like using. The only thing I like about it is their default design. Gnome looks really amateurish compared to it. Gnome-shell just feels snappier and better. (It also still have one design advantage - anti-aliased rounded window borders.)}

Update: I'm waiting for Gnome 3.4 to be added to ArchLinux stable Extra repo before I update my themes. I don't use Testing repos. It also seems that Ubuntu isn't that confussling any longer. Everything will probably work fine.
