Pixelmator on Tuesday unveiled Pixelmator Pro 1.0 Whirlwind, a high-powered version of its popular photo editing application for macOS. The app's interface has gotten an overhaul -- it's now in a single window with no floating toolbars -- and it boasts new nondestructive, GPU-powered image editing tools and enhanced machine-learning features. Nondestructive tools for color adjustments, effects, styles and layouts give users the freedom to make or remove changes at any point in the workflow of a photo editing project.
