[Usability] Closing windows with doubleclick

[Jan Rathmann <JanRathmann t-online de>]

Hello,

I hope this is the right place for my problem, I already have searched 
the mailing-list archives but didn't find anything related to this topic.
The problem is, that with metacity it seems to be not possible to close 
a window by double-clicking at the icon at the left top of the window, 
on all all other window managers I've seen so far (kwin, fluxbox, 
ice-wm, window manager of microsoft windows) this behaviour can at least 
be configured. Because it really restricts me at working, I was forced 
to use a different window manager with Gnome, but this is also of course 
not the perfect solution.
So what I wanted to ask is, if I have overseen a hidden configuration 
option of metacity, or, if not, if this functionality could maybe be 
added to metacity as an option, that could be enabled by users who need 
this feature.

Kind regards,
Jan
