Reduce title bar size on GNOME 3.X desktop

 I am currently using GNOME 3.4.2 / openSUSE 12.2 and I find it annoying that Adwaita theme makes all the Top / Title bars in all application windows ( browser, Nautilus ) look bloated and ugly. For sometime i was wondering as to how i can easily change the Title bar settings alone. I decided that I would have to change the window theme from Adwaita to something else , though i am not fond of changing default themes.

  Before changing the theme I wanted to measure the height of the title bar when Adwaita theme is used. I found a nice screen ruler called NRuler after a brief search on the internet. I downloaded the jar version of it and executed the jar . When I measured the height of the Title bar using NRuler I was shocked to find that it used more than 40 out of the 768 pixels available on my screen.

 I opened command launcher window (AlT+F2) and typed in the command "gnome-tweak-tool" to open "Advanced Settings" applet for GNOME 3.X desktop. I opened "Theme" settings and changed the Window Theme from "Adwaita" to "Crux".

 When i measured the height again i was relieved to find that title bar was only about 20 pixels now. I am hoping that the title bars will be better looking when i switch to GNOME 3.6 which would come bundled with openSUSE 12.3 .
