Gnome Shell Extension: Force Quit

Note: This is an archived post. Information may not be relevant now.

Force Quit is an extension that adds a ‘Force Quit’ button to the top panel of gnome shell, the UI of Gnome 3. Clicking the x icon from the left of the gnome-shell panel changes the cursor into a x. Then, click over a non-responding application to kill it instantly.

[Note: This extension isn’t maintained any more.]
