"Send URL" as browser extension

[clipperhouse]

An idea for your consideration: I often play MP4's directly in the browser. I would love to send the current URL in the address bar directly to the Chromecast.

(Interestingly, the Cast... command built into Chrome will mirror the tab but not send the URL.)

Going a step further, detect compatible URL file extensions on the page, and put a Cast icon next to them.
