Tangential, but the default breeze theme of KDE plasma desktop is really good. I want to thank everyone who worked on that. That was the first OS theme I looked at and thought ok - system ui is a solved problem for me now. I have completely stopped tinkering with KDE customization options since - the default just looks perfect.

It was kind of similar when I first looked at VSCode's default color dark theme and realized - I am never changing an editor color theme again - and I haven't.

Defaults matter - and I am happy to see open source tools like KDE ship with great usability out of the box.
