Same here with the muscle memory. It's nice to hear that Pixelmator is compatible with it. BTW, do you use it on Windows or on a Mac?
Whereas I often find myself having to search through help pages and forums when using Affinity Photo.
For many years I didn’t consider a computer a computer until it had Photoshop on it, but since moving to Pixelmator, Affinity and Figma I’ve been able to ditch Adobe completely.
