What is interesting to me is the intersection of all these perspectives about code and the user experience. I have taken quite a few photoshop classes through the years from the perspective of a photographer (as opposed to designer) and what always makes me smile are all the functions you are told never to use. The most basic of these is the menu choice under Image>Black & White. When asked why we should not use it the instructor invariably says, "Photoshop is a monolith of code and Adobe is terrified to remove anything for fear it will all come crashing down. So even though no one uses Black & White it will be there forever." I am told this is much of the reason that Lightroom was born. It was an effort to make a photographers tool that wasn't crushed under the weight of its own legacy code.
