Elementary is starting to actually look nicer than macOS. There's still some janky details here and there, but the overall design language is very nice.
It's a sign of how crappy mainstream UI design has gotten that the thing that is really drawing me to elementary OS are the gradients, shadows, and edges that give its UI sense of depth -- not the Linux underpinnings, multitouch, or "App Store". It makes the UI 1000x easier to grok at a glance than the flat crap Microsoft and Apple have been pushing out over the past few years, and just plain looks good! I'd love for it to kick off a move back to that kind of design, but sadly it doesn't look like that's the direction things are heading.
pop os puts a big ass orange line around the active window. its probably a bit gaudy but i love it.
it makes it so much easier to see where you're at, even at it the corner of your eye. i don't know if i could go back to other os's where the active window only gets a slightly darker drop shadow than the other windows.
Most tiling WMs have a similar feature, and you can adjust the size/color of the border and if it appears on all sides of the window or just some of them. I use Sway and have my border set to an aquamarine color. The border also gets used to show which way your container is split / where a new window will appear if you're focused on that window.
I just use the Arc GTK theme and use the kvantum Qt theme’s Arc preset. Makes both look pretty much the same. Qogir is another one that’s kind of cross-desktop.
