Chromecast a Camera Layout Tab

Could we get a feature in the NX Witness client to Chromecast a camera layout tab plus it's audio?

Chrome based web browsers have a Chromecast feature that allows you to cast a browser tab or the entire screen to an Android TV. Currently we've been using the browser to cast the entire screen and maximizing the cameras on a secondary computer monitor. The downside of course is we have to leave the browser running in the background and we tie up a monitor. If we close the seemingly empty browser window it stops the screen sharing.

It would be a lot nicer if we could screen cast a tab within NX Witness even when running in the background. It would also be good if the tab had a visual indicator when casting so we don't close it without thinking.
