The thing that really pisses me off is the flat design that is so popular now. It's so hard to tell when something is a button versus a label. I feel like I never know what is clickable or not.
the thing is that flat design is way more of a subtle art than skeumorphism, you have to really know what you're doing for it to work well.
With skeumorphism you just slap some shading on it and call it a day, for flat design you have to think about where things are placed and what precise colour they are compared to the background, which icons you use, etc etc..
It doesn't have so many essential modern features, kde has hdr, proper fractional scaling, mixed refresh rate displays and is much more secure thanks to wayland, plus the performance hit is tiny these days.
Wait, you can spruce it up? I've been running it stock for a year now. The design grew on me because it was installed on all the old desktops in my highschool, and I've had it on my laptop ever since.
