Agreed. They have a lot of the required plumbing now. There are some non-destructive editing workflows in GIMP.
I think holding back 3.0 for so long was a mistake. It no longer matters though. It is out now and it can be improved dramatically without such a long break between the dev version and stable.
We will see what the next couple of years brings.
I agree.
Just recently, I used GIMP 3.0 to create what will become a sticker on the side of a dozen hockey helmets.
It was a small project but it probably went back and forth a dozen times as each version delivered sparked new ideas or new questions on what was possible. Layers, filters, alpha channel, Smart Selection, and working with text and font outlines were all essential.
I don’t do all this stuff all the time. There is no way I would ever pay for Photoshop. Yet, my standard Linux install had everything I needed to get it done. And it was not that hard.
Truly amazing when you think about it. We are all so entitled.
