Frankly, the only way they could make X-Plane easier, is if they could read your mind.. P3D relies on plugins, addons, all kinds of things.. Really, it's just as complex, but ten years of the same or slightly changed interface is comfortable. When it was new we all had to learn it as well.. Xp11 is really easier to use that either fsx or p3d but it is new, so therefore, uncomfortable, even for us XP users since we're accustomed to much greater level of complexity and granularity.
