There is something to it when people say linuxers don't care about the UI. Of course, a generalization, as e.g. inkscape has tearable bars. But when we tried to redesign the whole UI, the sheer size of the code base didn't allow for big refactoring. OTOH, branching the code base by a single coder would have created a multi-year endeavour---just for the UI?
So, it's the casualty of doing coding in Linux, the missing time for big things, and the lack of professional (= paid) leadership, all a bit.
