There are valid points on both sides of that issue. On one hand, sophisticated image processing techniques require a level of user education that doesn't fit nicely into a UI. How to get the most out of the various tools belongs in the manual. On the other hand, Darktable's UI would benefit from some polishing, and perhaps a more gentle learning curve for beginners to become productive. This is very common in open source applications, as there tend to be more programmers contributing than UX designers.
