AirPlay Support

It would be great to see some sort of enhanced AirPlay mirroring support for Textastic iOS. Some apps have the ability to change what you see on the iOS device screen when mirroring is turned on. This would allow Textastic to take advantage of the larger (TV) screen's real estate while using the iOS device for controls/keyboard only. Maybe this could allow for multiple editing panels (ie HTML and CSS side-by-side)?
