What features would you like to see in Pixelmator Pro?
Whenever I launch Pixelmator Pro, it turns on the high performance GPU. While it's nice from the performance angle, it would be nice to be able to disable it to make the battery last longer.
Install gfxCardStatus. Choose "Integrated Only" then launch Pixelmator Pro. Then runs on integrated graphics only.
While I appreciate the suggestion, my experience with gfxCardStatus could be described as shaky at best. I just checked to see if they had a new release, it's been since August of 2013.
