I think, url placed at bottom should be hidden when there’s no input to browser window. On mouse move, keyup/keydown, etc. we could display this text. Why? You decided to always display urlbar, because protect users against hijacking. If user doesn’t interact with page, so don’t send sensitive data, there’s no reason to display url bar. Of course, some page could display fake news, so there’s still little problem, but this problem is very seldom.
