As a UI/UX designer myself (hobbyist, to be clear), I really like it.
There seems to be this notion in the homebrew/FOSS/Linux community that "wasted space" is always non-preferable. I can see this being true for some people, but I feel like a lot of people and band wagoning this opinion.
It's pretty universally known and accepted in the design community that padding is extremely important when it comes to helping your brain read and separate content. And to be fair, most non-tech people prefer space and padding in their applications to make things easier to understand.
I can be entirely off base here, but TLDR: I like padding and it's literally beneficial to helping your brain understand the layout of what you're looking at better.
The reason why I can't recommend YouTube music is that it uses audio from videos instead of playing the studio versions of the tracks. The fact that it makes me listen to those silly audio parts in music videos while I'm trying to listen to a studio release is terrible in my opinion, and I couldn't figure out a way to hide those results from search entirely. Does anybody know if they've fixed this?
