Your designers are morons
Your UI changes to reading PDFs online are...moronic.
The task bar at top is now approx. 6 inches...why so large?
I can tell you why: your designers are morons.
Is it not obvious that change only for the sake of change isn't a good thing? Hasn't the last 5-10 years taught us this, software-wise?
Your new UI is awful. The tweaks are moronic.
