I would be deliriously happy if vue can... do properly what it's supposed to do at the moment:)

In principle I think it should focus on its main objectives - creating images of nature. I agree a good terrain editor is very important. I think users should be able to create plants (veg type), not just modify them a  bit as is the case now.
I think the water editor was a step in the right directions, but I'm somewhat disappointed with it, perhaps I havnt mastered it fully yet.

I model things in Hexagon - it's far from being a perfect application, but I got it for $2 so I'm not complaining. It was very liberating to be able to make props the away I needed them for the image rather than adapt the image to whatever props I can find. I would like to learn to use blender, but somehow never get around to it.
I dont think Vue should direct their limited resources to duplicating in vue the modeling tools other programs already do well now.
