When the news of the introduction of a single-window mode in GIMP 2.8 hit the net it became clear what an incredible desire for something like this there was. The reactions have been overwhelmingly positive, and this really helps to motivate you to hack on it. The news also revealed an interesting but previously rather anonymous group of people: multi-window zealots despising the idea of a single-window mode in their beloved multi-window application. I suspect they don't realize that single-window mode is going to be optional...
I am happy to tell that the implementation of the single-window mode is progressing well.
