The initial beta design had so many obvious issues that it's wild that it made it as far as it did. Hell, the readability of many UI elements was obviously terrible in the initial reveal, where you'd expect everything to be shown in the best possible light.

Obviously Apple can improve things for the final release (and it seems like they're taking some steps in that direction). But these issues should have been identified long before the beta was released, and the fact that they weren't does not inspire confidence.
