Showing title on address bar is unnecessary. The title is always on the top of the webpage. URL is the only thing that should be on addressbar. That's how it works on desktop and every other place like file manager. That's the job of addressbar.
I want to see the website I am on while browsing. That's how I can know that I am on www.facbook.com and not some fake site like www.faccebook.com. If the url is hiddden, you could be redirected to fake site or an ad network.
So, atleast give an option to show URLs on addressbar instead of title of the webpage.
