just a quicky. If you use the xfce terminal and you like to have more then one tab-terminal open, you might have niticed the the middle button closes it, without confirmation… I just discovered that this annoying feature can be turned off.
Following the freedesktop spec, you can just edit the file .config/Terminal/terminalrc and set the option MiscTabCloseMiddleClick to False.
There are many other settings . The full list is here : http://docs.xfce.org/apps/terminal/advanced
