You can add custom stylesheets. In the next version I will add a submenu in the dashboard, so you can then activate or deactivate the javascript method ??

Steps to do for own stylesheet:
1. create wp-custom-login.css in you stylesheet directory (/wp-content/themes/yourcurrenttheme/wp-custom-login.css)
2. write something like that:

#login {
margin: 0 auto;
width: 275px;
}
