I've been looking for a 3rd party world editor, because WED doesn't have the features our designer needs. So I figured, why not request them for WED? I think it could help a lot of people anyway, even though I doubt they will be done in time for us to use. So here goes:

*Ability to "paint" textures onto terrain and surfaces with brush

* Different terrain/block manipulation tools:
-Raise
-Lower
-Smooth
-Bulldozer
-Spline (roads and rivers)
-Etc...

You get the idea. You see these sort of features in other engines, and I think they could make WED an awesome tool.
