T3D - World/Terrain/Material Editor & Precipitation Feedback

So I had my first stab at creating a terrain and mini level, and heres some feedback and suggestions on different aspects of the World Editor, that i think could modified to increase the usability and flexibility of the world editor. (Forgive me if any of these features are already in the engine and i couldnt find them).

1) Texture sizes for individual textures (Instead of just having a default size for ALL textures on the terrain each texture could have its own relative scale, this way you could paint huge rock textures that blend into small grass textures).

2) Tie the material editor to the terrain painter so that you can paint ANY material you have already made onto the terrain... It would be so much better if all materials were integrated simply all in the same place and there were many more options for them such as options to offset, tile, scale all the different elements of a texture like the normal and specular individually).

3) Brush dynamics (For painting on the terrain it would be VERY nice to have options like brush opacity, brush edge hardness, brush flow, brush alpha shape)

4) If you could make strings of objects similar to the road editor but for props and more generic so that it could be used to make more than JUST roads (pipe lines, train lines, fences, power lines etc.) I thought their was an object type road editor, however that seems to have been completely taken out and replaced by the decal road painter.

5) A key combination that you could press (EG Hold down CTRL) to invert the function of the terrain painting and texture painting (So that you can be raising terrain and then just press a button and press and it will lower it with the same settings).

<Then again from the original post>
So today i had my first tinker with Precipitation in the engine, and their are a few things i would like to pass back to GG. Firstly these arent jibes, but mere suggestions that i think will vastly improve T3D.

Suggestion 6) There is a "Use Wind" checkbox in the precipitation object, but i cant find out where the wind in a level is set? Does the Wind affect the grass swaying (which would be V. Cool)? bits like that.

Edit: i have just noticed this in the code.

//--------------------------------------------------------------------------
// Support functions
//--------------------------------------------------------------------------
VectorF Precipitation::getWindVelocity()
{
   // TODO: Fix me... this shouldn't be in the sky!
   //Sky* sky = gClientSceneGraph->getCurrentSky();
   //(sky && mUseWind) ? -sky->getWindVelocity() : VectorF(0,0,0);
   return VectorF::Zero; 
}

Whats the news on the wind? I can see some stuff in the Shaders for Ground Cover, will these take into account the values of the wind set up in WindEmitter (which i just found in the code)? And one quick last thing, how in the wetness and precipitation video, did Gerhard create them leaves blowing around?
