No workspace switcher or window list in gnome

Question

Hello,
My workspace switcher and window list have disappeared after a gnome update. When I look at /var/log/gdm/:0-greeter.log, I do not really know where to start.
/var/log/gdm/:0-greeter.log:
Window manager warning: Failed to read saved session file /var/lib/gdm/.config/metacity/sessions/10fb3f440368f4365712661658562916400000023630002.ms: Failed to open file '/var/lib/gdm/.config/metacity/sessions/10fb3f440368f4365712661658562916400000023630002.ms': No such file or directory

I mainly use a amall screened netbook and I'd very much like to get rid of the window bars in Gnome3 as I find they use up too much space and I'd rather use the keyboard to close the open windows and move the windows.
I really don't know where to look, I can't make any sense of the theme's file in /usr/share/themes/Adwaita/...
[EDIT]
I'll answer myself, as it was fairly easy after all:
The file is divided in several parts, each with setting for maximized or non-maximized windows etc. To have maximized windows have no title bar add in the line starting with <frame_geometry name="max":
has_title="false"
You can also specify the size of the bar with
title_scale="xx-small"
Avaliable are x-small, small, large, x-large etc.
could please tell me what is the name of the file to edit it,
thanks,
