While you make valid points, and without destroying your enthusiasm for suggesting improvements since you are so new to the forum, Graphisoft is a turgid enterprise scrambling to attract new users through enterprise appeal, not clever-versatile-guy-in-his-basement appeal.
As such, we see that thru the years, they focus on performance aspects, not interface apects.
And from an old guy to a new guy, everything seems simple, but assigning the correct priority is hard.
Another factor that you might consider is that users clamouring for features are people who have already purchased the program. Who cares about THEM?
