The Logoutwithoutbackup plugin does simply, what its title says. It will give you an button in cmsimple when loggedid that will allow you to log out, without creating a new backup of your content. This can be useful when only changing some settings (plugins or cmsimple) or styles.
The latest version of the plugin can be downloaded at http://www.infantilo.110mb.com
