The best thing about this is the fact that it’s free and open–source. To compare it to Adobe Photoshop, I don’t think it’s ready. It makes a really convenient tool for when you’re starting out with designing and editing simple images for personal publication. But like some users here, I agree to the observation that it’s rather difficult to create a smooth, intuitive workflow.
