Implement OS-X driver as a real screen, rather than a barely-configurable AirPlay display.
I have a dual-screen DisplayLink dock. When I plug it in, I have to explicitly enable it as an AirPlay target, and set "it"* to be used as a separate display.
Even when I do this, one of the displays refuses to be not-a-mirror, and I have to use SwitchResX to coerce my built-in retina display to use my external screen's native resolution.
Seriously, just get a dual-screen dock and a MacBook Pro and see what I mean. It's terrible.
- "it" makes little sense, as there are two screens attached - but there's still just one AirPlay target
AirPlay API doesn’t enable rotation. There isn’t more we are able to achieve on 10.13 last builds without OS changes.
The more adequate API was re-featured in 10.14 Mojave and we have been able to avoid AirPlay API and come back to a better feature set, including rotation. We are also improving on that feature set.

To clarify: I can rotate the "Built-in Retina display", but the mirrored screen does not get rotated. The separated screen does not have a rotation option, even when you do the "hold cmd+option" trick, nor does it have rotation options in SwitchResX.

Additional information: it's impossible to rotate my screens this way, which is irritating, since I was hoping to inverse-mount my screens on my desk.
