I did it this way as the latest version of elementaryOS Luna also has window buttons this way and as minimize button is also obsoleted in gnome shell, we should get accustomed to it. Btw, if you want you can easily edit the theme for your preferred button layout under "Emerald theme Manager > Edit Themes > Titlebar > Title-bar Object Layout". Thanks for appreciating my work.
minimize obsolete in gnome-shell? why haven't I noticed this yet? I still have it... granted you have to enable it but it's there. Anyway great theme and as a suggestion (personal preference to be more exact) make the borders slightly thinner.
Personally I love gnome-shell, fits my needs extremely well
