Yeah I'd love to prefer KDE, but GNOME is closer to what I'm used to (Mac OS). Pity it's not that good and written in JS.

I've been hoping Cosmic DE improves enough to be usable.

It doesn't matter that it's JS, they have their own, performant interpreter for it and it's a limited subset of JS. And that's just one layer, the rest is actual compiled code, increasingly Rust.

I was skeptical, too, but it allows for some serious visual tweaking beyond what KDE allows without rewriting code.
