Global Menu is the globally-shared menu bar of all applications launched in your desktop session.
There are several advantages by adopting a shared global menu bar in Gnome (thanks Matthew for organizing these):
* It works better with narrow windows, because the width of the menus isn't limited to the width of the window. (This is a problem for Gimp and Inkscape especially.)
* It's less confusing --- when two menu bars are visible on-screen at once, sometimes people choose the wrong one.
* Global Menu is the first step to move toward a Document Centric Desktop Environment which is, according to us, a long-term trend in DEs.
