If you click this button, the toolbar is instantly restored from that backup file, without any confirmation. \n 'REMOVE icon' - this removes the icon that is on the further right side of the toolbar, it always asks for confirmation before doing this. As a safe guard this button can't delete below a certain number of icons. \n 'ADVANCED' - this option allows the edition of the text configuration file that has all of your desktop's toolbar icon's configurations. Manually editing this file allows the user to rearange the order of the icons and delete or add any icon. A brief explanation about the inner workings of the text configuration file is displayed before the file is open for edition. \n Warnings: only manually edit a configuration file if you are sure of what you are doing! Always make a back up copy before editing a configuration file! " --center --length=50 --width=600 --button=gtk-quit:1;
