Show normal website to logged in users? should not exclude Admin

This is a great plugin, but there is one thing that I think you should address asap:

The toggle “Show normal website to logged in users?” when false should exclude admin accounts so that admins can continue to check their site updates while the maintenance mode is active.

Actually (as mentioned by others) I would like to see the ability to set a role or capacity by which logged in users are shown the site and everyone else is shown the message.

Thanks
