[Plugin: Simple Login Log] Log out data would be nice

I thought about it when I initially designed the plugin, but I wasn’t sure how accurate and useful it would be. First of all, a lot of people don’t log out. Eventually their session will run out, but that is not a logout action. There is no way to log an event when user leaves the site or closes a browser, nor it’s a logout action either and can be not user’s intent. So… the only logout action that could be specifically trackes, is when user clicks the logout button. I don’t think I ever logout from my WP sites on my personal workstation… ever.
