I love the new look of the PRV. The aim assist - very useful, midi blobs - very cool looking, free hand drawing of controller data - excellent (I remember an early version of Sonar or maybe back as far as a Cakewalk version had the same functionality, shift drag for straight lining even. Nice to see it back...)
But one thing bothers me...
... doesn't Apple have a patent on rectangles with rounded corners
