Really excited about Global colors!
Just a few notes:
1. The new Color Picker which pops up when selecting Add Global Color from the palette's hamburger menu is oddly sized, too wide. Also the color well is a rectangle while everywhere else in the UI it's circular.
2. The color of the noise slider doesn't match the selected color:
3. Also, the type on my non-retina mbp is blurry in the button labeled Edit Global Color, which appears under the new Tint slider in the Color palette.
