It was amusing for a while, and at this point it is just sad. Every so often, maybe the Gimp team itself puts out a survey, or external groups do some analysis. The results are consistent in that the Gimp UI is just bad. Frequently the survey results specifically and overwhelmingly offer a path forward: make the Gimp behave like Photoshop.
Now, I understand that the Gimp is light on developers So it might be a simple labor issue in getting fixes in. Or there are fixes ready to go, and the Gimp team is as obstinate in their UI as have been suggested by many others. Either way, no change happens.
Note to UI/HCI academics: if you actually want to better a project, choose anything but the GIMP. You would have a better chance of getting patches accepted for ed(1).
