I don't use UFraw which is too complicated for me too. But, I don't find  
full satisfaction "in Digikam way of Raw developping", because I never  
succeed to get an image wich approach enough of the camera proceed  
version, using only with RAWtool parameters and have to apply "post  
treatment" with the raw tool when I open a NEF file in editor. The matter  
for me here is the "post treatment" tab isn't present in all the tools  
which call the RAWtool (in batch RAW conversion tool for example).

So I use CaptureNX2, which reproduce the same development than the camera  
(it's normal because it has the technical data to do this) when I want a  
final use picture. And sometime digikam because it's faster than CaptureNX.

To share my own experience about embed JPG in raw file, i think the NEF  
produced by my D200 contain a thumbnail version and a preview version  
which is (for the dimension) between Thumbnail and RAW data.
