I first got depressed about NXG at one of the CAB sessions at a CLA Summit. It was on UI improvements with NXG. More modern UIs is something that could be significantly improved over CG. Think of all the techniques demonstrated in web pages or smart phones. At the very least, I was interested in the improved menus NXG would have (icons? Tip strips?).
Instead I sat there looking at a giant skeumorphic dial. Lots of detail, sharp and pretty. And resizes, which is nice. But nearly useless to me, as I've had no need of dials in decades. And as far as I know, NXG has yet to even have short-cut menus on controls, let alone have any improvements.
It is seriously sad that vector graphics resizability is the only thing NXG has going for it, UI-wise.
