feature request

It would be great if I could specify a background color and an image with the image overlay over the background color.
Also, if I could specify a location for the Logo, that would be nice.
Lastly, if I could specify Top or Bottom for the login dialog, it would allow me to move it so as not to block my image.
Thanks for a great plugin.
