The curves/histogram feature in Picture Windows is just *such* a
beauty, isn't it?  I also rather like being able to do *everything* in
16-bit-per-channel mode.  

But I miss layers, and I most super especially miss adjustment
layers.  I like non-destructive editing.

Now *there's* a realistic assessment!

I've really gotta try a partitioned flow.  It bothers me that my black
ink bottle goes down *so much* faster than the others. 

Um, you mentioned a "quad purge image", implying that it printed
things using the 4 inks individually.  Got an image to offer?  I'm
assuming it would look like bars in each of the CMYK colors?
