If you'd put a part of the effort that you're currently putting toward these suggestions for changing Terragen, into helping out in say, my retroreflective shaders thread, I'd be more inclined to be sympathetic toward your views on how this program, which does what it does better than any other software, could be improved. Until I see some jaw-dropping renders and associated tgd's, or some practical solutions to shader requests, all I see is a bunch of new guys whose job or hobby isn't terrain modeling and rendering, who are going to lobby for changes that, since they don't really know what they're doing, will wreck TG.
