Group Windows on a Taskbar in Gnome (on Debian
GNU/Linux) in Vista like fashion
I wanted to have my gnome windows be handled in a Vista / XP like
fashion in other words I wanted my Gnome to Group Windows (that
means if many Windows originating from the same source program then
let them be grouped in one Window so any time you press that Window
a menu pops up letting you choose between the desired Window). This
window management aproach has one main advantage it saves space on
your desktop and least but not last makes it much more
ordered.
Here are the steps you need to follow to achieve Gnome Group
Windowing.
1. Right click on the dotted section
(that's just to the left of your windows list section)
you should find that between "Show Desktop"
button and the rest of the windows buttons.
2. Select "Preferences" there and then choose according to your preferences
either:
"Group windows when space is limited" or
"Always group windows".
