Wayne, I have stated many times, that my aim is not to do things for prettyness sake, but to make things more easy to identify by groups and appearance. If at the same time you can make it look good the all the better.
My comment about traditionalists is more about that they cant understand that if something isnt grey, it isnt good. Lets face it, if we all had cars that were only useful, but had no prettyness about them, then life would be quite boring, and we might as well all drive around in the one style car.
Many of my screens may not be every ones taste, but they are proof of concept and have inspired others to go out and do better than mine.
Just by doing screens has bought in a lot of changes that make mach a better program. I know of quite a few things that have been implemented as a re********* of my hassling, of recent sliders has now been intrduced too. The fallout from pushing the limits a bit, actuall gives even the traditionalists a better program, not that they would know it, admit it, or even observe it.
The science of ergonomics as you put it, is an evolving science, and something we must keep experimenting with, in order to build upon our existing knowledge.
