I suspect one of two things will happen in a year:
1. people will get used to it and wish everything had blurry nondescript icons designed with the big grey crayon and giant tabs .
2. It will get better.

My guess is the second option. They've done a great job in the past. In the meantime, version 14 works fine. There aren't features that are "must have" in 15 so it can be worked out. The dark themes and stuff have potential.
