For laptops with RGB-backlit keyboards, Plasma has gained the ability to keep the backlight color in sync with the active accent color!
That’s insane, this is why I both like KDE and the open source community in general. An option that only 1% of users will ever be able to use. And, of those only ~50% max who are able to use it will actually want to use, but someone has made it an optional feature anyway as a passion project. I will never use this but I’m delighted it exists.
