Read most of the comment, was hesitated. Then thought "it can't be that bad". Ok, it is that bad. I absolutely hate extra round corners and extra margin in the windows. Sigh.

It’s just change. People complain every time the UI changes on anything.

People will get used to it. Apple will refine some things over time.

It will be ok.

I usually agree (and enjoy reading angry threads years later), but wasting screen real estate and getting measurably worse in terms of accessibility is simply not a good design decision.

I guess you can bookmark this thread and set a reminder to revisit it in 5 years and see how it went.
