i haven’t messed with ue5 yet beyond 5 minutes but my immediate impression is that the flat UI is harder on the eyes for long development days. I like big, unique, colorful icons that are easy to spot so that you dont really need to search with your eyes so much.
I was kinda surprised so many people thought that wass a big improvment, or that the old style was bad. I wonder if there was any empirical testing involved to confirm benefits of flat modern style.
