I feel UI trends have gone in the direction of making things worse, not better.

I remember when it was pretty much unanimous that “mplayer” was beautiful in all its square corners glory, while “Windows Live Media Player” was seen as a horrible abomination.

Now it feels like everyone is on board with inefficient UI designs like the latter for some reason.

I don’t understand the posh stylistic decisions around padding, rounded borders, etc. How do those things make the UI better exactly?

As someone who used low resolutions for most of my University years (I did my thesis in a tiny ultralaptop), I relied heavily on a custom gtk2 theme I had to write to remove most of that padding that made the UI feel so unnecessary and my screen so cramped.

Gnome now pushing for removing theming completely and relying on just color scheme customization feels totally backwards to me. I don’t have an answer for OP sadly… other than just using terminal / tui apps more whenever possible.
