The editor is very very user friendly, and super fast (took it 10 minutes to generate this texture)
It can import and edit heightmaps on the fly in 3d, and has a very versatile texturing tool.
I liked it so much, that I decided to remake one of my older maps, just to see how good it would look, and because that map wasn't properly finished and fine tuned.
The results speak for themselves, download it and I hope you have as much fun playing it as I did in making it :)
If you have any questions regarding the WIC map editor, feel free to ask :)
