Sharing clipboard, files, notifications, controlling cursor and keyboard from your phone, controlling media - all of that just works really well, without online accounts, on your local network.
Sure, there's Apple Continuity, but looks like it was released 2014 (KDE Connect - 2013) and it's tightly locked to the Apple ecosystem. And yes, the 2013 version doesn't have the same feature parity or stability as the current one, but that's ok because we're not discussing bugfixes or polish.
It's innovative enough that GSConnect is the Gnome implementation of the KDE Connect.
KDE Connect is over 10 years old by now. Hardly new. I also think it's sort of an extension of Apple's Messages app on MacOS, which let you send and receive messages through iMessage from a Mac, and thus pick up where you left of with your phone. That might be a stretch though, since KDE Connect and later Continuity does a lot more (although I'd be very surprised if Continuity wasn't viewed as that inside Apple at that time).
I'm also pretty sure the basic feature set you're mentioning, like clipboard and file sharing, using your phone to control your desktop, was part of the 1.0 release. Are there any features in KDE Connect that are new-ish?
That said, props to KDE for actually making a feature that hadn't been done before. But if KDE Connect is the most recent example of genuine improvements in the desktop experience that aren't just fixes, that goes to show that nobody's actually doing anything significant (in a good way) to the desktop experience.
