Captive Portal: Easy accessible Logout page instead of Logout pop-up window
I suggest a functionality that allows using a logout page instead of a pop-up. The reason why I am suggesting this is that pop-ups are often blocked or do not work. A logout page would open on a new tab or window and ideally easily accessible via an alias URL e.g. by just typing "logout" as the URL. So people can call the page back when they have accidentally closed it.
