Lightwave and vue have interfaces I dislike in the extreme -- so does photoshop. There is no answer to the interface issue that will please everyone. none. Those interfaces are not options for me. In short, they suck (tis an opinion, as any thoughts of design on interaface are, since it is an aesthetic issue regardless). To make it a professional application? why, professional users. And it has them already.

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
