What features would you like to see in Pixelmator Pro?
Pixelmator Pro has batch editing via Automator which actually covers almost every feature we've added to Pixelmator Photo. Although Pixelmator Photo is a bit more flexible and has direct library integration — but other than that, the ML Enhance and ML White Balance are there, color adjustment presets are there, image resizing is there. ML Crop (and cropping in general) is missing, but that's about it.
Yep, Change Type of Images is also available as an action! There's a tutorial about it here, actually.
