The most important new feature in 5.22, to me at least: I can finally uncheck "Unhide when window wants attention" so that my task bars don't cover my programs any more whenever someone sends me a message on [chat program].

It's a tiny thing but it drives me nuts (and luckily for me it has also been driving someone working on KDE nuts so they fixed it!)

At the same time, the fact that this is my biggest complaint regarding KDE Neon should be a clear indication that I'm quite a happy user in general :)
