I did the first step I mentioned for dealing with d.nviz from the GUI. I removed the button for d.nviz and for nviz from the layer manager and added menu entries for both under a 3D rendering entry under the file menu.
Now both commands can be launched in their generic forms from the GUI without an error. I'll still look into what it might take to do a TcloTk wrapper for d.nviz. I also tested multiple layers in nviz on the Mac with a version of 6.3 compiled on Friday. You can open multiple raster files, multiple color rasters, vector lines and vector points either by entering them into the GUI dialog before starting nviz or by adding them once you start nviz. This used to generate an error but works fine now.
