I try not to comment on things like UI features, because I have no clue how difficult it is to make changes. But it always blew my mind that custom wallpapers in the background wasn't a thing at launch. Or at the very least, basic color changes to the background (like Vita).



I know it's not massively important, but it does go a long way for people in terms of making the UI seem more interesting. I personally love PS4's UI (I prefer it to X1, I like how slick and efficient it is. It's quick, and easy to navigate. It just works). But I would have preferred the ability to change it up a little bit.
