[8.10; gnome] window-tab modification: an "X" as shortcut for closing a window

[oponto]

Hiho,

I want to set a small symbol "x" on the left right of a window (of ANY program, also nautilus etc.) as shortcut for closing this window/program. I mean the window in the window panel, not the window itself, which has an 'x'.

It should be independent from the theme.

What I want is compareable with tabbed browsing (especially the opera theme meguiddo x' .

It just a detail, but it would increase my personal working speed a lot.
Hopefully I didn't miss a menue point that allowed this configuration.

thanks :D

Ok, got to set up a symbol there, edited any file recommended in the deeps of the web.

But how to assign a feature to make the button that it closes the application/window ?

Any Linux programmers here who can tell me which file to edit ?
