Do you really think that? To me, this is just a collection of really old stuff and features that should be a matter of course.
Case in point: "the headline feature" (adjusting the color temperature of your display depending on the time of day) is something that has been around for years one way or the other on all operating systems.
Or take: "Bookmarking webpages in Web now takes a single click." Hasn't that been the case since, like, always? Even if I'm wrong, I would hardly file such a feature under "really cool stuff".
But not in Wayland. I'm happily using Redshift in Cinnamon (one of the other things keeping me on Cinnamon), but the fact remains that having it built into the distro makes it more readily accessible to everyone.
Windows 10 doesn't have that. What's your point?
(Also, FWIW, Win10 insider builds do have it out of the box.)
Shipping this feature out of the box with an OS install started happening only recently (e.g. Night Shift came to iOS only 1 year ago, Windows 10 is getting it just now, AOSP has a "secret" knob to turn it on and it's enabled in 3rd party ROMs, etc).
EDIT: Nevermind, this ticket looks like it might: https://github.com/MarshallOfSound/Google-Play-Music-Desktop...
> It looks like it needs to be hard-coded for compatibility with every app
By using a white-list? I thought it worked with every app which uses the MPRIS DBus interface.
I'm holding out at the moment, as it's missing one feature from Cinnamon that I really like (the ability to launch and control any audio player from the sound icon in the tray), but when Fedora 26 launches I may finally have to switch over.
I hope that Canonical shifting back to GNOME will further its development under Wayland and not spend a crapload of time doing more work for Mir.
