I've recently begun learning Fusion for its fantastic parametric capabilities but I'm seriously considering hiring out my left hand! It has nothing to do except hit alt-shift when I pan. I come from a Rhino 3D background and while that program lack serious parametric tools it has the most intuitive and flowing interface option based on the command line. Everything can be done from the keyboard, and shortcuts -- even a series of shortcuts-- can be customised. No hunting for pull-downs or clicking somewhere specific when you're done. Following their example would make Fusion so much of a joy to use not to mention SO much faster.
