Pro image editing tools like Adobe Photoshop are vital in the creative world, but let's face it: not everyone can justify paying $10 or more per month, every month, just to get more than rudimentary tools. You may not have to in the near future, though. The Pixelmator team is previewing Pixelmator Pro, an upgraded version of its long-serving (and historically more affordable) Mac app geared toward serious creatives. The editor promises many of the features you'd expect in a high-end app, and a little bit beyond -- there's even a dash of AI-like technology involved. The software is non-destructive (that is, you can always reverse changes), with a heavily revamped interface that merges everything into a single pane.
