Looks nice, unfortunately I'll have to stick with however Google's alternative is currently called since Google Cast is the strictly better model for these types of devices in my view, compared to Airplay.
Google Cast runs the player on the cast target and only uses the device that initiates playback as an optional remote control that can be disconnected without interrupting streaming.
Airplay requires the controlling device to remain available throughout, in my experience; receiving a phone call, watching other media etc. on my phone isn't possible without interrupting playback. (This might have changed in one of the last versions, but that needs app support, and not knowing what to expect on a per app basis is at least as bad, if not worse.)
