There are plenty of GNOME Shell themes with transparent panels, and I might want a transparent window border / titlebar theme to go with it. The closest thing I can think of is Emerald, but that only works with Compiz AFAIK and GNOME Shell only works with Mutter.
Since the release of Ubuntu 12.10,
To enable Window Titlebar transparency in Ubuntu 12 onwards:
You can change the window border transparency using the gconf-editor. You can change the window transparency for all the window borders or for active window borders. To change the window borders transperancy you need to have the gconf-editor installed.
To install the gconf-editor open a terminal window (press Ctrl+Alt+T) and copy+paste the following line:
To start the gconf-editor press Alt+F2 and type: gconf-editor.
When the configuration editor is open click on apps -> gwd and change the value of the metacity_theme_active_opacity and the metacity_theme_opacity to a value lower then 1.0. To change a value all you have to do is double click on the name and change the value in the edit key window.
metacity_theme_active_opacity: changes transperancy for active window borders
metacity_theme_opacity: changes transperancy for all window borders
