Whoops, I edited to state that OP didn't feel entitled to me in the meantime. Sorry for this. It's more the "surprise about some obviously, severely underfunded project missing features is not very impressive" part. To be clear, I'm almost 100% sure the OP comment was written with good intent.

I don't work on the Gimp, I've read developers working on it at length, I think as a developer reading this comment I would be thinking "Well, we do what we can". Jehan, who wrote the post, contributes to the Gimp thanks to donations to his Ze Marmot project, his team cannot pay itself very well. They are going out of their way improving the Gimp anyway, indeed prioritizing features they need the most most certainly. But you can do only so much.

It might just be a matter of form/formulation. But it matters, because people won't take the time analyzing a comment for several minutes to completely put themselves in the commenter's shoes.

edit: you can respond by clicking on the "X minutes ago" link I think, but I saw your edit :-)
