I usually do a duplicate in the first place so I have the original file, and 
then the processed ones. This way I can see the amount of processing in each 
image without exporting any image, just having different xmp, one of them with 
an empty history.

I'm still thinking about this. Of course, it's a very necessary feature. Maybe 
digikam should show #xmp views instead of #rawfile views for raw files. Or, 
maybe just saying that "xmp" it's an image format that should be read by 
digikam, but dont know if this would work or it will continually generate xmp 
files...
